Insects — Boundless diversity

Insects are by far the most diverse group of living organisms. There are over 30’000 species in Switzerland, or approximately ten times more insects than plants! In addition to their spectacular diversity, insects have a significant impact on our environment and daily lives.

On this website, we regularly publish insect news from all fields of research. Let yourself be inspired!

Insects account for the majority of animal species. Beyond this diversity, insects impress due to various remarkable facets of their biology, as well as far-reaching interactions with other organisms. Insects provide key ecosystem services, and are of central importance for humans.

Insect species are currently endangered worldwide. It has hence become more important than ever to understand more about the diversity, evolution, distribution and ecology of these fascinating animals.

Since the founding of the society in 1858, the SES has encouraged the study of insects through the publication of the “Fauna Helvetica” book series and the journal “Alpine Entomology”, the organization of annual meetings and the support of various research groups. All of these activities have the same objective: to create an active network of entomologists and other entomologically interested people.
