Swiss Entomological Society

The Swiss Entomological Society (SES) fosters cooperation among both professional and amateur entomologists and promotes the scientific study of indigenous insects.

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!

Cratschla 2/19: Ökologie in der alpinen Zone

Die Artenzusammensetzung auf Berggipfeln verändert sich rasant. Die Verbreitung invasiver Arten und die Einflüsse des Landschaftsmanagments auf alpine Weiden machen ihrerseits die ökologischen Veränderungen sichtbar. Die soeben erschienene Herbstausgabe 2/2019 der «Cratschla» widmet den Schwerpunkt diesem Thema. Ausserdem stellt ein Artikel die Resultate des Projekts «AkIdEn» zu Akzeptanz, Engagement und Identifikation in Biosphärenreservaten vor.

The European environment — state and outlook 2020

Europe will not achieve its 2030 goals without urgent action during the next 10 years to address the alarming rate of biodiversity loss, increasing impacts of climate change and the overconsumption of natural resources. The European Environment Agency’s (EEA) latest ‘State of the Environment’ report states that Europe faces environmental challenges of unprecedented scale and urgency. The report says, however, there is reason for hope, amid increased public awareness of the need to shift to a sustainable future, technological innovations, growing community initiatives and stepped up EU action like the European Green Deal.

Willkommen im Reich der Insekten!

In no other animal group are so many new species described every year. Not surprising, given that insects represent approximately 80% of all known species. Nevertheless, it is remarkable that so many new species are discovered in a region as well studied as Switzerland.

The description of new species represents a fundamental part of taxonomic research. Equally important is our understanding of the biology, distribution and ecology of these species.

Since the founding of the society in 1858, the SES has encouraged the study of indigenous species through the publication of books and a journal, 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.
