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).


The types of 982 species (represented by 2,063 specimens) are stored separately and belong to the following superfamilies:

Tenthredinoidea 86 spp.662
Ichneumonoidea 452 spp.533primarily deriving from coll. Habermehl (1858-1940)
Chalcidoidea 23 spp.63
Chrysidoidea 18 spp.26
Scolioidea 13 spp.28
Formicoidea 25 spp.73
Vespoidea 57 spp.85
Sphecoidea 11 spp.31
Apoidea 297 spp.562

Important parts of the collection:

  • Coll. Schenk (1803-1878), received in 1968, containing a total of about 13,750 specimens, only exceptional labelled. This collection is stored separately.Coll. Rebmann (1896-1970): received in 1970, containing a total of about 10,000 specimens including numerous types and paratypes. This material is incorporated into the main collection.

    Coll.Heinrich (1903-1978): 1977/78 acquired, containing primarily Aculeata with main focus on Apoidea, including numerous types. This material is incorporated into the main collection.
