- Polypores host species rich insect assemblages, but relatively few polypore species have been studied in detail. We investigated insect assemblages associated with the fruit bodies of Daedalea quercina, a specialist species on oak in southern Sweden. Fruit bodies (n = 228) were collected from 25 nature reserves and woodland key habitats, and were taken into the laboratory to collect emerging insects. A total of 245 insect individuals were recorded, belonging to at least 45 species. The numerically dominant fungivores were the tineid moths Montescardia tessulatella (n = 38 individuals) and Nemapogon fungivorellus (n = 10) and the coleopteran Ennearthron cornutum (Ciidae) (n = 44). Altogether 40 individuals of hymenopteran parasitoids were recorded, belonging to Braconidae (Exothecinae, Microgastrinae and Rogadinae, altogether 6 spp.), Ichneumonidae (Banchinae, Cryptinae and Orthocentrinae, altogether 4 spp.), Torymidae (1 sp.), Perilampidae (1 sp.) and Scelionidae (1 sp.). Most of the remaining insect species are not specifically associated with fruit bodies, but occupy many types of decaying material. In conclusion, D. quercina hosted a low number of insect individuals in general and only a few coleopteran species. The fungus apparently has only one specialist species, N. fungivorellus, which is a near-threatened (NT) species on the Swedish red list; the record from Norra Vi is the first from the Jönköping. The overall low number of insect individuals and the dominance of Lepidoptera among the fungivores is possibly explained by the tough fruit bodies of D. quercina, which only moths are able to utilize; fruit bodies which had already started to rot were devoid of moths.

Tidskriftsartikel (refereegranskat)abstract
- Caterpillars of the mining micro-moth Phyllocnistis labyrinthella feed on leaves of aspen (Populus tremula) and are often parasitized by eulophid wasps. The parasitoids are a potential important cause of death for the miners. During 2009-2011 we collected mined leaves from an experimental stand of aspen trees in Västerbotten. Adults emerged from 17-35 percent of the mines and of these every second to third specimen appeared as wasps. These wasps represented seven species of eulophid parasitoids of which three were new to Västerbotten: Chrysocharis nitetis (Walker), Cirrospilus diallus (Walker) and Cirrospilus pictus (Nees). We include an identification key that may be used to identify these eulophid species.

The European birch sawfly, Arge pullata(Hymenoptera: Argidae), in Sweden, and the firstnational record of its parasitoid Scolobates testaceus(Hymenoptera: Ichneumonidae)

Tidskriftsartikel (refereegranskat)abstract
- The European birch sawfly Arge pullata (Zaddach) was found for the first time in Sweden in the early 2000s. According to a report in the local newspaper it was present on the Falsterbo peninsula, Skåne province, from 2000 at the latest, and in the following years a number of records were reported from the same restricted area. Subsequently it has expanded its range in southern Sweden. It is unusual that a sawfly receives public attention, but in the case of this species its presence is of general interest because of the toxic properties of its larvae, which can be consumed by cattle and pets. Here we give a short description of thebiology of the species, its spread in southern Sweden, and report the first record in Sweden of its parasitoid Scolobates testaceus Morley, which is also the first record of S. testaceus from A. pullata. We speculate that this and possibly other natural enemies have attenuated the spread and build-up of large populations, which were feared when the species was first detected in the country.

Occurrence of the hermit beetle (Osmoderma eremita), in Sweden.

Tidskriftsartikel (refereegranskat)abstract
- We have compiled data on the occurrence of a threatened beetle, Osmoderma eremita, in Sweden. The species inhabits tree hollows with wood mould. The data were compiled from field surveys conducted in 1993-2003, using pitfall traps at 401 localities and using wood mould sampling at 104 localities. We have also gone through published data and all larger Swedish museums and registered old records. O. eremita was recorded at about 30% of the field surveys. In Sweden, oak is by far the most important host tree species, but the beetle has also been found in other deciduous trees, such as beech, alder, ash and lime. Currently, 270 localities with Osmoderma eremita, defined as records of living adults, larvae, fragments of adult body parts, or excrements situated at least 1 km from each other, are known in Sweden. 129 of these localities are records of live beetles or larvae made after 1990. The species is found in the southern third of Sweden only, and there are more localities in the eastern part compared to the western. The great majority of the localities have been discovered during the last ten years. At some of the localities only excrements or fragments have been recorded, and the species might actually be extinct at some of these localities. Due to low search intensity historically, it is impossible to use these data to discover any changes in the distribution or occurrence over time. Because old, hollow oaks were much more frequent 200 years ago, we suggest that the species has decreased severely in Sweden since that time. Today, old oaks are rarely cut down but instead lack of grazing cattle is a threat because many sites regrow with dense tree stands which outcompete the old hollow trees. Many local extinctions could also be expected during the next few decades, because many of the localities have too few hollow trees and are too isolated. At many localities, lack of younger trees which can take over the role as host trees when the present trees die will also be a problem in the future.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- We describe the work with donated insect collections at the Swedish Museum of NaturalHistory (NRM) in Stockholm, Sweden. The museum receives donations yearly fromamateur entomologists, and they are an important contribution to the enrichment of thecollections. For the collector it is satisfying that a public institution takes on the long termresponsibility of safeguarding the scientific value in a collection, curating and making itavailable for study. Significant donations in the last years include that of Lars Huggert(Hymenoptera, Coleoptera), Hans Bartsch (Diptera) and Anders N. Nilsson (aquatic Coleoptera)to name a few. The curatorial and digitizing workload at the Entomology collectionare unfortunately not matched by staff funding, and as at other European museumsvolunteer work constitute vital and invaluable help. We acknowledge especially some ofthe volunteer work in the Coleoptera and Hymenoptera collections. Recently we have engagedwith amateur entomologists by organizing taxon-specific workshops at the museumwhich has stimulated exchange and collaboration. The Hymenoptera-day was visited by 30participants, and the Diptera-meeting by 49. As an example of what happens with a donationonce it reaches the museum, we describe the work with a recent Coleoptera collectiondonation by Jan Olsson, Vallentuna. A few highlights from the unidentified material,including the Archostematan beetle Priacma serrata (Cupedidae) and the false jewelbeetleSchizopus laetus (Schizopodidae), are presented as they were new to the NRM collections.We also bring attention to two new websites: www.naturarv.se is the webportal presentingdigitized material in Swedish natural history collections. Both metadata on specimens andphotos are made searchable here. We also launch a new webpage at www.nrm.se/insektsdonationerwhere we write about new donations to the Entomology collections, with JanOlsson’s Coleoptera collection first out.

- We report the first finding of the antlion Distoleon tetragrammicus (Fabricius, 1798) fromSweden. Several adults of the species have been collected or photographed on the island ofGotland in the Baltic Sea, between 2017 and 2021. The first finding is from Tofta skjutfält,a sandy military training ground vegetated with pines and mixed forests on the west coastof Gotland. Based on multi-year observations at the same locality as well as video recordingof an egglaying female it is clearly a resident population, even though larvae are yet to bedocumented. Distoleon tetragrammicus is not previously known from any of the Nordic orBaltic countries. The species is common in southern Europe with a wide distribution acrosswest palearctic and becomes rarer towards central Europe. The closest known locality isan outpost population on the Hel peninsula on the Polish Baltic coast which we speculateis the most probable source, 240km south of Gotland across the Baltic sea. Previously butthree species of antlions were known from the Nordic-Baltic countries, all belonging to thetypical pitfall trap-building tribe Myrmeleontini and subfamily Myrmeleontinae: Myrmeleonformicarius (Linnaeus, 1767), Myrmeleon bore (Tjeder, 1941) and Euroleon nostras (Geoffroyin Fourcroy, 1785). Distoleon tetragrammicus belongs to subfamily Nemoleontinae (tribeNemoleontini) with larvae being ambush predators without the behaviour of building pitfalltraps. We provide an identification key, as well as studio and field photographs of all fourNordic species. The quality and conservation value of Tofta military training ground localityfor insects is discussed with reference to other rare species.

Tidskriftsartikel (refereegranskat)abstract
- The yearly Swedish entomology meeting 2017 was organized by the local entomologysociety of Gotland, on the northern part of the Baltic island Gotland near Bunge, 4-6 August.One thematic excursion was focused on aquatic insects, especiallly aquatic beetles,bugs and dragonflies. A shallow pond, Äskåkersvät, with Characeae in an open grazedlandscape with high natural values was studied. Äskåkersvät lies just adjacent to the largerarea around lake Bästeträsk which is the focus of a pilot study evaluating its potential asa future national park. The pilot study is undertaken by Gotland County AdministrativeBoard, the Swedish Environmental Protection Agency, Region Gotland and the SwedishAgency for Marine and Water Management. Here we give an annotated report of the 103species found: 69 species of water beetles (out of which 34 were Dytiscidae), 20 speciesof aquatic or semiaquatic bugs (out of which 10 were Corixidae), and 14 species of dragonflies.These include Hydrophilus piceus and H. aterrimus redlisted in Sweden (both asNT), and Dytiscus latissimus, globally redlisted (VU). We also noted the noble crayfish,Astacus astacus (redlisted as CR in Sweden) and the European medicinal leech Hirudomedicinalis (redlisted as NT globally). The blue emperor dragonfly (Anax imperator) wasnoted, a species first recorded from Gotland in 2002 and we present a graph on its increaseand spreading on the island since. The number of species found in spite of a relativelymodest collecting effort at a suboptimal time when many species may be in pupal stage outof water as witnessed by many teneral individuals, indicates a species rich locality withhigh natural value. The stoneworts (Characeae) vegetation certainly contributes to this, forinstance vouched for by the occurrence of specialists as Haliplus confinis and H. obliquuswhose larvae feed on stoneworts.

Åkerjordfly, Agrotis exclamationis, identifierad som värdart för svävflugan Villa hottentotta med hjälp av DNA streckkodning (Diptera: Bombyliidae).

Tidskriftsartikel (refereegranskat)abstract
- In this study we identify Agrotis exclamationis (Linnaeus, 1758) as a host species for the bee y Villa hottentotta (Linnaeus, 1758) in Sweden. Host use and speci city for bee y species are generally very poorly known, why the hatching of a bee y of the genus Villa from an unknown Noctuid pupa caught our attention. The parasitized Noctuid pupa was found in a garden in Staffanstorp, Skåne (Sweden), in May 2015 and kept in a jar to hatch. The bee y hatched in June leaving two empty exuviae in the jar. DNA was extracted sepa- rately from both excuviae to identify the y and the host using DNA Barcoding. A 600+ bp long sequence of the gene Cytochrome oxidase subunit 1 was sequenced for both samples and queried against the reference library BOLD (www.boldsystems.org). The Noctuid host pupa was unambiguously identi ed as the common Noctuid species Agrotis exclamationis. The sequence was identical to the most common haplotype over much of Europe. The bee y pupa was identi ed as Villa hottentotta, the most common Villa species in Sweden. This added a new Noctuid species to the list of known hosts for V. hottentotta which also includes several other Noctuid genera as well as a Geometrid moth. Belonging to the sand chamber group of bee ies where the female scatter the eggs on the ground while hovering, the active host-seeking rst instar planidium larvae bene ts from having a wide host range to potentially encounter in the substrate zone.

Tidskriftsartikel (refereegranskat)abstract
- The pine-tree lappet moth, Dendrolimus pini (L.), belonging to the family Lasiocampidae has a wide distribution in Eurasia. In Sweden it is normally found up to 61°N and normally occurs at low densities. In central Europe there have been several reports of outbreaks in historical time. In Sweden the last known outbreak before the one reported here was in 1938-40 in Värmland. In this paper we report a recent severe D. pini outbreak that was discovered in 2012 on the small island Furuskär in the Stockholm archipelago. The distribution of the damage on the island as well as a detailed inventory of larvae and pupae on individual trees is presented. Several photographs are presented to illustrate the damage. In the paper we formulate and try to answer several questions that arose as a natural consequence of this rare event: Why was this particular island hit? What are the causes behind the outbreak? What will happen to the trees and the vegetation on the island? Will the outbreak continue? Will the outbreak spread?

They have all been collected using car net in an area next to the lake Häckeberga in Scania in southrnmost Sweden. The area is characterized by beech forests and marshes. Also, when working with Swedish specimens of Euconnus, we found that E. pragensis have been incorrectly reported from Sweden and has to be omitted from the Swedish list.

- The fauna of hoverflies in Boreal and Arctic parts of Scandinavia is still very poorly investigated. Therefore we performed an 11 year survey of the hoverfly genus Platycheirus Lepeletier & Serville, 1828 along the Caledonian mountain chain in Sweden (from Värmland northwards to the Torneträsk area). During 2003-2013 we annually performed two trips in order to survey various areas and to collect flies by netting. Altogether 150 localities were visited and a total of 1862 Platycheirus-specimens belonging to 40 species were collected. Two species were recorded for the first time in Sweden: Platycheirus carinatus(Curran, 1927) and P. magadanensis Mutin, 1999 and 74 records were new for various fauna-provinces. Four main areas were selected for comparative studies on distribution, habitat, local migration and environmental influences on population fluctuation of Platycheirus-species. We noted that males hatch earlier than females and the latter sex await the maturing anthers of their feeding plants. Moreover, Platycheirus-species in alpine and subalpine terrain seem to be very cold resistant and active at air-temperatures around 10O C. Environmental disturbance within the subalpine and northern boreal vegetation zones, e.g. cutting of woods or constructing of slalom slopes, creates new flower rich habitats and therefore support the population sizes within this assemblage of overflies. The observed distribution of northern Platycheirus-species along the Boreal and Arctic parts of Scandinavia reflects its worldwide Holarctic and Palearctic relations.

- We report the first finding of the grasshopper Aiolopus thalassinus (Fabricius, 1781) inthe Nordic countries. Two migrating individuals were attracted to light at a known hotspotof migrating moths near the southernmost tip of Gotland in the Baltic Sea, 8th of August2020. End of September hundreds of individuals had made landfall in a bay not far from thefirst locality. The mass occurrence followed after days of easterly or southeasterly winds,a strengthened high pressure over Russia, and an early morning with low-lying clouds.Aiolopus thalassinus is a long-winged grasshopper with strong flight capacity and a widedistribution across the Old World. It also shares some of the density-dependent behavioraland physiological characteristics of the migratory locusts. In Europe the northern continuousdistribution limit stretches through south Germany and middle Poland. The findings onGotland follow the first record in Lithuania, 2019, and a recent trend of expanding rangein south Germany which indicates a species expanding its distribution due to a changingclimate. The findings also show that this is a species capable of swarm migration and crossinga minimum of 170 km of open sea when winds are favorable.

- A brief history of entomology at the Swedish Museum of Natural History for the period 1915-1923 is presented in chronicle form. The time circumscription has its background in a recent 100th anniversary of the current museum building, for which there was work on an anniversary book, which has not appeared, and this is based on a contribution originally intended for that book. It concerns primarily the Entomology department (which ended as a unit in 2013 when it was part of a fusion into a Zoology department) but also includes the Entomological Society of Stockholm to the extent it has been based at the museum, as well as insect-related work in other museum departments. The chronicle gives plenty of examples of research and researchers, other staff and routines, collection growth and management, collecting expeditions and publications, work environment issues and everyday life at the department.

Tidskriftsartikel (refereegranskat)abstract
- In the decades surrounding the turn of the century 1800, several of the leading entomolo- gists in Sweden were also involved in Christian sects following the doctrines of Emanuel Swedenborg. This has often been noted by historians, but only occasionally by entomolo- gists, and has never been subjected to closer study.This paper sketches the history of Swedenborgian entomology in Sweden, from natural history students in Skara in the 1780s, over the utopian plans connected with the Swedish involvement in the colonial adventure in West Africa, to the Linnaean and Swedenborgian societies in Gotland and Stockholm, the coleopterist stronghold on the plain of Västergöt- land, and eventually to a last survivor in Fåhraeus’s old days.The two early key figures both came from Västergötland, Adam Afzelius and Leonard Gyllenhal. In the African adventure, the naturalists inspired by Swedenborg were Afzelius and Anders Sparrman. Gotland became a stronghold where Pehr Hemming Odhner and Gustaf J Billberg tutored Olof I Fåhraeus. In the Swedenborgian circles in Stockholm, Billberg, Carl Johan Schönherr and Carl E Deléen were prominent. Then Gyllenhal and Schönherr were both in Västergötland and Fåhraeus in Göteborg. Short biographies of these persons are given and their interconnections laid out.The Linnaean perspective on nature had one of its cornerstone in a religious sense of wonder when facing nature, which is known as physico-theology. In the generation after Linnaeus, some prominent naturalists turned away from wonder and speculation, in paral- lel with ongoing enlightenment campaigns against superstition. Especially in the tradi- tional academic natural history environments in Uppsala and Lund there was a reaction with many people turning to the new ideas of ”romantic biology” or ”Naturphilosophie” in Oken’s sense. Whereas in the non-academy-based, more bourgeois and amateur, natural history circles in Stockholm, in Västergötland and eventually in Göteborg, the maintaining of the sense of wonder in Linnaeanism seems to have fit better with the Swedenborgian movement and Swedenborg’s ideas

- The question of who can be considered Sweden’s first female entomologist is not easy toanswer and depends a lot on criteria; here it leads to a more general survey of women in Swedish entomology. Several persons who are candidates for being considered entomologist pioneers are presented, and the conditions for women to engage in entomology are briefly discussed. Such candidates include the following persons. Queen Lovisa Ulrika, Linnaeus’ benefactor, had an insect collection. The first female member of the Entomological Society in Stockholm was Signe Nordenskjöld in 1892. While Cecilia Andersson seems to be the first independent, active female insect collector in Sweden, in the early 20th century. Ida Trotzig collected Lepidoptera in Japan for the Stockholm museum. At that time, preparator Signe Ramberg and illustrator Therese Ekblom at the Stockholm museum were the first female professional entomologists. Only later, the entomological societies included somewhat larger number of female entomologists, and the first woman to get a PhD in entomology in Sweden was Christine Dahl, who also became the first female entomologist full professor.

- During the last decades a striking decline has been observed for wild bees throughout central and north-western Europe, including Sweden. in an area of 64 km' in the parish of Stenbrohult, southern Smaland Andrena hattorfiana, Andrena humilis, Nomada armata and Panurgus hanksianus were studied (in Sweden red-listed as VU, EN, EN and VU). We present occurrence patterns in relation to habitat types for these bee species. They are to a large extent dependent on the herbs Knautia arvensis (occurred in 80% of the 1 x 1 km squares in the study area in 1970-74), Leontodon hispidus (52% of the squares) and Hypochoeris radicata (48% of the squares) for pollen. Andrena hattorfiana was recorded from 72 habitat patches (453 individuals recorded from 38 (59%) squares of 1 x 1 km) and its cuckoo bee Nomada armata from five sites (9 individuals in five (8%) squares of I x 1 km). Unmanaged grasslands supported the largest numbers of Andrena hattorfiana in the study area, but traditionally hay meadows with late harvest supported the highest density and the largest local populations. Panurgus banksianus was recorded from two localities (>30 individuals in 2 (3%) squares of I x I km). Andrena humilis was only found on meadows with late harvest (>51 individuals in 3 (5%) squares of I x l km), frequently visiting flowers of Leontodon hispidus. This is currently the only known larger population in Sweden. The patches with the largest numbers of bees, regarding both species richness and number of individuals of these four species, were meadows managed with late summer mowing. On flower rich meadows in Rashult (in the central part of the study area) all four bee species occurred together. No threatened bees were found at heavily grazed localities.

- During the last couple of years leaf-edge-cuts, typical of Otiorhynchus, a genus of wingless weevils, have been discovered on ornamental shrubs, especially on lilac (Syringa vulgaris) and privet (Ligustrum vulgare). An inventory was made in gardens in west Scania 2009. The results show that we in Sweden have a new species of wingless-weevil, Dodecastichus inflatus (former known as Otiorhynchus inflatus). Further more, the weevil Otiorhynchus smreczynskii was shown to be established in a much larger geographic area than previously known. This species was the most common on lilac and privet and caused the majority of the damages. The morphology of these two species is described. The extension and appearances of the damages have been documented in order to see if different weevil species make different types of edge-cuts. Several weevil species have spred in gardens in our neighbouring countries during the last decades. The species most likely to occur more frequently in Sweden are described. These six Otiorhynchus species, that are potential pests in our gardens, are: O. tenebricosus, O. salicicola, O. crataegi, O. dieckmanni, O. aurifer and O. armadillo.

- Six species of beetles new to the Swedish fauna are presented. Megasternum immaculatum (Stephens, 1829) (Hydrophilidae) has been confirmed to occur in the north of Sweden in natural conditions as well as in the south, living in compost. Carpelimus punctatellus (Erichson, 1840) (Staphylinidae) was found using suction sampling in a xerotherm ruderal area in the city of Malmö. Meligethes sulcatus Brisout de Barneville, 1863 (Nitidulidae) have been shown to occur on Lamium album in eastern Småland. Diaclina fagi (Panzer, 1799) (Tenebrionidae) was found in numbers in the province of Öland in agricultural remains with mouldy grains and peas. Psylliodes reitteri Weise, 1888 (Chrysomelidae) has been found in Scania on one occasion in two specimens in a suitable habitat. Parascythopus intrusus (Kono, 1948) (Curculionidae) was found in Scania in the vicinity of a garden center.

Tidskriftsartikel (refereegranskat)abstract
- As a result of a careful examination of the available Swedish material of the genus Clambus Fischer von Waldheim,1821 (Coleoptera: Clambidae), our current understanding of the Swedish Clambus fauna is revised. A total of 1844 specimens were identified from museum specimens as well as private collections, resulting in eight species belonging to the Swedish fauna. In the past there was confusion about the identity of Clambus minutus (Sturm, 1807), and its distribution data were later on incorrectly transferred to Clambus nigrellus Reitter, 1914. This is now resolved and the corrected distribution for C. nigrellus is presented herein, making it clear that this is a species with very few Swedish records. Another species for which there was a lot of confusion is Clambus gibbulus (LeConte, 1850). A number of previously identified records were incorrect and this species actually has very few old records, but it has recently been collected using window traps in burnt forests. Clambus pallidulus Reitter, 1911 and Clambus lohsei Meybohm, 2004 are recent newcomers into Sweden and they are now for the first time added to the Swedish fauna. Updated distributions of all of the Swedish species are provided and an illustrated determination key is included.

- Hoplothrips caespitis (Uzel, 1895) and Megalothrips bonannii Uzel, 1895 were recorded for the first time in Sweden, and the species are also new to Scandinavia. The species were found in Scania (Skåne) in the southernmost part of Sweden in dry grassland habitat and close to a small river. Two additional species Aeolothrips astutus Priesner, 1926 and Odontothrips biuncus John, 1921 are new to the province of Scania. Notes on biology, host plants and distribution in Sweden and Europe are given.

- Thorybothrips unicolor (Schille) and Tmetothrips subapterus (Haliday) have been recorded for the first time in Sweden, and the former is also new to the Nordic countries. Thrips dilatatus Uzel, Bolothrips icarus (Uzel) and Haplothrips acanthoscelis Karny are furthermore reported for the first time from the province of Öland. The rarest of the reported species are T. unicolor, which is included in the polish Red List as critically endangered (CR). Notes of distribution in northern Europe and in the Swedish provinces as well as host plants are provided for all species.Many of these new findings are from areas connected to Ölands steppe-like formation (the Alvar) on limestone bedrock, which is known for its interesting diversity of insects. In recent years thrips have been collected by using malaise traps, sifting and sweeping in these areas, which has led to new insights into the Swedish Thysanoptera fauna.

- Wetland area has decreased dramatically compared with preindustrial times, and in manyagricultural areas almost all wetlands have been drained to gain cropland. The trend hasin recent years been reversed because society has realized the many benefits of wetlandfunctions, such as for nutrient retention and flood control. In this study we inventoried 75 wetlands in Uppland and Halland for insects and spiders with Malaise traps, pitfall traps andsuction sampling. Most included wetlands are constructed, because the main purpose was toexamine if these wetlands also can be good for arthropod diversity, but we also included somemore natural wetlands as comparison. In total, we identified more than 25,000 individualsof more than 900 species of Coleoptera, Araneae, Diptera and Heteroptera. We found onenew species for Sweden, Hilara manicata Meigen 1822, and 37 new regional records. Alarge number of species found are considered threatened or else rare. Some wetlands closeto Mälaren were particularly interesting, with three species (Hypsosinga heri (Hahn 1831),Rhaphium antennatum (Charlier 1835) and Bagous robustus Brisout de Barneville 1863)that have no records nearby during recent times. These and other species found in the studyshow that constructed wetlands can provide good habitats for arthropod biodiversity andrare species, particularly if wetland shores are grazed and trampled by cattle.

Tidskriftsartikel (refereegranskat)abstract
- Today it becomes more and more common during archaeological investigations to use insect analyses when interpreting the natural and cultural environment during prehistoric and historic times. The composition and amount of insects in the deposits is dependent on both what insect species that is deposited and the preservation of the remains. It is therefore important to understand how different insects are preserved in archaeological deposits. Results are presented from analyses of recently dead insect remains in two wells and a stable floor, in south central Sweden. These data where compared with the results from Iron Age deposits. These data yield clues regarding the deposition of insect remains in prehistoric rural sites. It is concluded that ground-dwelling insects dominate records from wells and beetles enter the well accidentally and drown. Because of the absence of beetles associated with substrates like dung and wood in the modern deposits, in opposite to prehistoric, it is concluded that these groups of beetle species probably either are present around an uncovered well or are secondarily deposited through dumped material if the well head is covered and enclosed. The indoor environment of a stable is characterized through more remnants of insect species from the local human environment and wood, but also incorporates species randomly trapped during local flight.

Longhorn beetles in Sweden – changes in distribution and abundance over the last two hundred years
- 2010
-
Ingår i: Entomologisk tidskrift. - 0013-886X. ; 131, s. 241-512

Tidskriftsartikel (refereegranskat)abstract
- The abandonment of traditional agricultural practices and the introduction of large-scale industrial forestry has transformed landscapes and changed the conditions for wood-living organisms. This study examines changes in distribution and abundance of the 118 species of longhorn beetles (Col. Cerambycidae) recorded from natural habitat in Sweden over the 19th and 20th centuries, based on extensive surveys of museums, private collections and information in the literature, all in all more than 57 000 specific records compiled by 1400 collectors. The primary results are presented as maps of species’ distributions (-1900; 1901-1950; 1951-1975, and 1976-2000), population size indices (PSI s) based on species frequencies in subsets of the total material obtained by comparable collection methods, and estimates of abundance compiled from a succession of insect faunas spanning two centuries. Changing practices and preferences of collectors are examined in order to interpret the maps and indices and separate real changes of distribution and/or abundance from artefacts due to sampling biases. Appendices include the phenology of individual species and sources of data in the literature. Distributions of most species have changed little during our period of study, and 45 of 103 species are still assigned to the same category of abundance today as in the faunas from the early 19th century. Similarly, tests and interpretations of the PSIs indicate that the abundances of 31 out of 76 analysed species have been quite stable since the 1950s. Other species seem to increase - 32 are considered more abundant today than in the early 19th century faunas, and 17 of the 76 analysed species appear to have become more common since the 1950s. However, there have also been substantial negative changes: 26 species are categorised as less abundant today than in the early 19th century, and 5-10 of these have probably gone extinct. Furthermore, tests and interpretations of the PSI s indicate that 16 of 76 analysed species have decreased in abundance over the last fifty years. Some of these are associated with burnt trees, a handful develop in large diameter sun-exposed dead oak wood, others utilise dead wood of lime, a couple live in open, grazed coniferous forests, two species mainly develop in old construction wood and one species is primarily found in old-growth spruce forests. Close to half of all Swedish species of longhorn beetles are red-listed. However, our analyses indicate that few red-listed species meet the IUCN thresholds for population decline, suggesting that the thresholds are set too high to detect declining longhorn beetles (and perhaps insects more generally), but also that some red-listed species seem to increase and should be removed from the list. Our results also indicate that red-listed species whose narrow distributions have been the same for a long time may be limited by other factors than substrate availability, and therefore be more resilient to habitat change than their red-list classification suggests. Conversely, species with recently contracting ranges of distribution may be even more at risk than their threat categories imply. A final section briefly discusses monitoring of future trends and gives some suggestions on how conservation measures may be designed to better meet regional conservation needs
