Die Anzahl verlässlich gemeldeter Taxa (Arten und Unterarten) der Curculionoidea aus der Schweiz beträgt momentan 1081. Funde von Orchestes calceatus (Germar, 1821) werden hier er…

Osmia (Melanosmia) nigriventris (Zetterstedt) is a predominantly boreoalpine megachilid bee species, whose biology is poorly known due to its pronounced rarity all over Central Eu…

Das ursprünglich aus den Südwestalpen beschriebene Taxon Nematopogon adansoniella (de Villers, 1789) wird neu bewertet. Auf Grund von DNA-Barcodeuntersuchungen sowie morphologisch…

The mid-term impact of forest fires and windthrows on species compositions in the insect orders Neuroptera, Raphidioptera and Mecoptera was assessed in Swiss forests using standar…

We revise the Alpine bee taxa related to Andrena bicolor (Fabricius, 1775), including A. montana Warncke, 1973 and A. allosa Warncke, 1975, the status of which has remained conten…

Understanding why and how multiple species manage to coexist represents a primary goal of ecological and evolutionary research. This is of particular relevance for communities tha…

Hoplitis robusta (Nylander) is a rare and poorly known osmiine bee species occurring in the subalpine zone of the Alps. The discovery of two nests of H. robusta in a thin branch o…

Here, we investigate about 5500 previously unidentified specimens from the collection of Gerhard Bächli. A total of 108 agromyzid species were added to the fauna of Switzerland. C…

Both molecular and morphologic characters support the reinstatement of Leuctra biellensis Festa, 1942 as a valid species distinct from Leuctra nigra (Olivier, 1811). Genetic dista…

A description of the male adults of five Chaetocladius s. str. species (C. castellae sp. n., C. lencioniae sp. n., C. lodscrozetae sp. n., C. macunensis sp. n. and C. muttensis sp…

The flat bug fauna of Switzerland is still insufficiently studied. We describe the first records of Aradus angularis J. Sahlberg, 1886 and Quilnus marcosi Heiss & Baena, 2006 (Het…

Cultivated and suburban areas are usually considered unfavourable to the vulnerable components of biodiversity and regarded as not interesting from a conservation point of view. H…

Phylogeographic data indicate that DNA differences consistently exist between the North American and European allopatric populations of Gymnopus confluens. Conversely, pairing exp…

The sooty bark disease (SBD) is an emerging disease affecting sycamore maple trees (Acer pseudoplatanus) in Europe. Cryptostroma corticale, the causal agent, putatively native to …

In the new range, invasive species lack their specialist co-evolved natural enemies, which then might be used as biocontrol agents. Populations of both a plant invader in the intr…

Available information on the typification of the name Ranunculus rionii in the literature is scarce and misleading. Previously claimed type collections indicate Lagger as the coll…

We combine multivariate ratio analysis (MRA) of body measurements and analyses of mitochondrial and nuclear data to examine the status of several species of European paper wasps (…

Despite its wide, almost worldwide distribution, the mayfly genusCloeonLeach, 1815 (Ephemeroptera: Baetidae) is restricted in the Western hemisphere to North America, where a sing…

Sexual dimorphisms in shell-bearing snails expressed by characteristic traits of their respective shells would offer the possibility for a lot of studies about gender distribution…

Scelionid wasps are arthropod egg parasitoids, many of which are relevant to global plant biosecurity. However, the scelionid fauna of Germany has not received much attention from…

The Europan species of the genus Tetrastichus (Insecta, Hymenoptera, Eulophidae, Tetrastichinae) are revised with 93 species, including 50 species described as new. The revision w…

Parasitoid wasps of the genus Pteromalus play an important role in biological pest control, however, the genus includes a large number of cryptic species, which makes reliable ide…

Future forest composition is uncertain in many areas due to climate change. The spread of non-native species adds to these uncertainties, particularly in forests recently colonise…

Invasive knotweeds, native to Eastern Asia, are among the most dominant plant invaders of European and North American temperate ecosystems. Recent studies indicate that one cause …

The nomenclature of Eastern Asian populations traditionally assigned to Cardamine flexuosa has remained unresolved since 2006, when they were found to be distinct from the Europea…

Given the limited success of past and current conservation efforts, an alternative approach is to preserve tissues and genomes of targeted organisms in cryobanks to make them acce…
