- Dramatic declines of some arthropod populations have recently received a lot of attention. Identified declines have mainly been attributed to changes in agriculture, climate, pathogen prevalence and light pollution, as well as cross-regional effects of, e.g., drifting pesticides. However, the overall picture is complex and debated, and there is a need for systematically collected long-term data, not least from areas relatively unaffected by humans. We monitored the abundance of arthropods (mainly insects) in subalpine birch forest in Swedish Lapland over a period of 53 years (1968-2020), in an area comparatively unaffected by human activities. Arthropod abundance was assessed by yearly systematic counts on 24,000 birch shoots, in the second half of June. Animals were categorised into 17 different groups directly upon counting, dependent on taxonomy and life stage (imago, larva). Overall, there was no significant change in arthropod numbers. Nor did estimates of the total biomass of arthropods (using group-specific indices of the mass of individuals) show any significant trend. Accordingly, there are no signs that the arthropod abundance or biomass on birch in this subarctic study site has gone through the same declines as have been reported from sites in other habitats. The reason may be that the impact of factors identified worldwide as drivers of arthropod declines so far are small or non-existent because of the low human population density in this area.

- Bumblebees are a key taxon contributing to the provision of crop pollination and ecosystem functioning. However, land use and climate change are two of the main factors causing bee decline across the world. In this study, we investigated how the flight period of bumblebee spring queens has shifted over the last century in Sweden, and to what extent such shifts depended on climate change, landscape context, latitude, and the phenology of bumblebee species. We studied ten species of bumblebees and used observations from museum specimens covering 117 years from the southernmost region in Sweden (Scania), combined with citizen-reported observations during the past 20 years across Sweden. We found that the flight period of bumblebees has advanced by 5 days on average during the last 20 years across Sweden. In the agriculture-dominated region of Scania, we found that in the late 2010s bumblebee spring queen activity in simplified landscapes had advanced by on average 14 days, compared to 100 years ago. In addition, in simplified landscapes the flight period of early species was significantly earlier compared to in complex landscapes. Our results provide knowledge on the intraspecific variation of phenological traits, indicating that early species (often common species) exhibit a higher plastic response to the environment, which may facilitate adaptation to both climate and landscape changes, compared to the late species of which many are declining.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Insects and other invertebrate remains from the coffin of a 17th century bishop in Lund Minster, S Sweden
- 2020

Ingår i: Journal of Archaeological Science. - : Elsevier. - 2352-409X .- 2352-4103. ; 31

Tidskriftsartikel (refereegranskat)abstract
- An extraordinarily diverse and well-preserved material, including the remains of 47 insect taxa and 12 taxa of other invertebrates, extracted from the 17th century burial of Bishop Peder Winstrup in Lund Minster, is presented and discussed in terms of the treatment of the body, activities connected with the burial and faunal significance. The invertebrate assemblages include species from gardens, insects feeding on living plants as well as dried or decaying plant matter. Many of the species are regarded as closely associated with humans (synanthropic), and a number of these are associated with outbuildings, such as stables and cellars. The absence of species associated with cadavers (necrophilous taxa) in the studied insect material is significant. The most plausible explanation is that the bishop died, and was buried during the winter, when such species are inactive, and thus precluded from colonising the body. A number of species were recorded which are today rare or very rare in southern Sweden. This is a strong indication that they once were more common and widespread, perhaps due to a greater prevalence of their preferred habitats. Sweden’s earliest fossil bedbug is also amongst the finds.

Nya och förväntade öronvivelarter (Coleoptera: Otiorhynchini) på prydnadsbuskar i Sverige

- 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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Svenska skalbaggar 3 – släktet Clambus
- 2022

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.

Tidskriftsartikel (refereegranskat)abstract
- 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.
