Cryocollection of Aquatic Insects
We actively maintain a collection of frozen specimens of aquatic insects from Europe, the Himalaya, and the Afrotropical region. The focus is on adult and larval caddisflies (Trichoptera) but also comprises stoneflies (Plecoptera), and mayflies (Ephemeroptera). In total the collection contains 5000 specimens and species series suitable for DNA work and morphological study.
The bulk of the collection is formed by Tenthredinidae, Ichneumonidae, Chrysididae, and Apoidea of the western palaearctic. The research activities of the scientific staff cause a permanent increase of the collection. The collection contains at least 9,900 species besides additional unnamed material, primarily enclosing Ichneumonidae and Apoidea. Moreover, the collection also includes a lot of completely untreated material collected in different zoogeographical regions (i.e. different islands of the South Seas, collected by N. L. H. Kraus).
