Entomologischer Verein Krefeld
German learned society
The Entomologischer Verein Krefeld (EVK) is an entomological society based in Krefeld, North Rhine-Westphalia, Germany. Founded in 1905, it keeps meticulous records and specimens of the area's insects, a collection curated since 1987 by entomologist Martin Sorg.[1][2]
The EVK is known in particular for a study it conducted, published in PLOS One in 2017, that demonstrated a 75 percent decline in flying insect biomass in 63 nature reserves in Germany between 1989 and 2016.[3][4] The paper became the "third most frequently cited scientific study" of 2017 in the media, according to The Economist.[5]
