The core is a selection of nests of various insects purchased by Alexander Kohts in Germany from the company of W. Schluter, as well as nests of Hymenopterans collected individually in the 1930s by entomologist A. Gutbir, commissioned by Alexander Kohts.
A significant part of the collection consists of nests of different species of Hymenoptera and termites, collected by Sc.D. Maria Sadovnikova-Koltsova. The specimens were selected mainly to be displayed in the future permanent exhibition of the museum.
