- 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.

- 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.

- 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.

- Four species of Coleoptera, not previously reported from Sweden are presented; Euconnus campestris (Schaufuss, 1866) (Staphylinidae: Scydmaeninae), Scopaeus ryei Wollaston, 1872 (Staphylinidae: Paederinae), Acritus homoeopaticus Wollaston, 1857 (Histeridae) and Ephistemus reitteri Casey, 1900 (Cryptophagidae). 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.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- En regnig och blåsig höstdag den 13 november1916 invigde kung Gustav V Naturhistoriskariksmuseets nya lokaler i Frescati, en monumentalbyggnad på granitsockel med mörkt rött tegeli fasaderna (Fig. 1). Den fantastiska kupolenmed sitt koppartak och glas har nyligen genomgripanderenoverats och framträder i skick somnytt. I kupolen var det tänkt att en Foucault´spendel skulle hänga. Diskussioner om pendelnhar nyligen åter initierats av Riksmusei vänner.De rikliga utsmyckningarna är värda att tittaefter. De flesta missar nog tyvärr de två bamsigabjörnungarna som pryder entrén från stora vägennär museet fått nya infarter. Samma år utkom boken”Naturhistoriska riksmuseets historia, Dessuppkomst och utveckling” utgiven av KungligaVetenskapsakademien. Boken kan sägas varasamlingarnas historia. Där beskrivs hur museetär årsbarn med Vetenskapsakademien, som närden grundades 1739 av bl. a. Linné också inrättadeett skåp för naturalier. Av den anledningenfirade Naturhistoriska riksmuseet sitt 250 års jubileummed pompa och ståt år 1989.Mindre än ett decennium efter att NaturhistoriskaRiksmuseet flyttade till Frescati, år 1925,bildades föreningen Riksmusei Vänner somstödjer museet på många olika vis. Vi vill medden här artikeln dels informera om föreningenoch uppmuntra till medlemsskap, dels beskrivaföreningens koppling till svensk entomologi ochsärskilt Renè Malaise.

- 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.

- 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
