STRI's Insect Collection holdings consist of the STRI Synoptic Insect Collection and more than 7 affiliated research collections.

STRI Synoptic Insect Collection was begun on Barro Colorado Island in 1977 by Robert Silberglied and Annette Aiello as a general collection to give researchers an overview of the BCI insect fauna and to permit preliminary identifications for research vouchers.  Years, later the collection was moved to the Tupper site where it now occupies 150 Cornell drawers and includes voucher material from STRI visitors and staff.  The collection is strongest in Asilidae (robber flies), Pentatomidae (stink bugs), Reduviidae (assassin bugs), and Passalidae (betsy beetles) groups that were targeted by visiting specialists. (Tupper 207)

Henry P. Stockwell beetle collection occupies some 200 drawers, including about 80 drawers of Curculionidae (weevils).  More than 70% of the material is from Panama.  The collection includes about 100 paratypes representing about 15 species. (Tupper 207)

Henk Wolda light trapped insects from various stations in Panama, especially Barro Colorado Island (BCI), are estimated at 2500 Homoptera (Auchenorrhyncha only), 1000 Cerambycidae, 300 Blattodea, and unspecified, but smaller, numbers of Scarabaeidae, Elateridae, Chrysomelidae, and various other coleopteran families. (Tupper 207)

David Roubik & William Wcislo Neotropical and Paleotropical Hymenoptera comprises roughly 40,000 specimens of wasps, parasitoid wasps, ants, and bees.  All major bee families are represented, but primarily Meliponinae, with approximately 500 species from Panama and Costa Rica, 400 species from South American, and 80 species from Malaysia and Thailand, including approximately 1000 types, 50 of which are Meliponinae and Halictidae. (Tupper 207 & 503)

Annette Aiello reared Lepidoptera as well as some other orders, occupies 75 Cornell drawers. The collection includes mounted head capsules, pupal exuviae, cocoons and other abandoned parts. (Tupper 222 and 207)

Donald M. Windsor Wohlbachia bacteria study vouchers consists of several cabinets of general insects tested for the presence and strain of Wohlbachia bacteria. (Tupper 229 and 207)
