The systematic collections of the Yale Peabody Museum’s Division of Entomology comprise over one million curated specimens.

Division holdings include important collections of lepidopterans, arachnids, Orthoptera, Coleoptera, water beetles and midges, and specialty collections on evolutionary themes. Recent acquisitions also include historically important collections from other institutions.

The Division also maintains a general entomological library of periodicals, books and reprints that includes coverage of arachnology donated from the Alexander Petrunkevitch Library.

The Yale Peabody Museum’s collections are available to legitimate researchers for scholarly use. Loans are issued to responsible individuals at established institutions. Loans and access to the collection can be arranged through the Collections Manager.
