Free-living flatworms, also known as turbellarians, are abundant and key components of aquatic habitats. They play vital roles in food webs and contribute to ecosystem health. How…

Although Europe is the best-explored continent entomologically, major gaps remain, especially in alpine regions and within taxonomically challenging “dark taxa”, such as parasitoi…

The presence of the rare alpine insect Hemerobius schedli Hölzel, 1970 was confirmed with preserved museum specimens in Basel and London. In addition, live specimens were collecte…

Überprüfte Sammlungsexemplare und aktuelle Funde des besonders selten gefundenen und nur äusserst lokal vorkommenden Adosomus roridus aus der Schweiz führten zur Entdeckung von Ei…
