This collection contains catalog records from the University of Michigan Museum of Zoology’s Insect Division’s specimen collection. Many specimen records include a specimen and label data image. The database currently contains about 400,000 specimen records out of the estimated 3 million estimated specimens in the collection. Some records contain complete collection, preparation, and taxonomic detail, while others only have a specimen data image and limited taxonomic detail. Records include specimen information from the early 1800’s through the present and are of global distribution. Most of our databased or digitized records currently are of Orthoptera (grasshoppers, katydids, & crickets), Odonata (dragonflies & damselfies), and Hymenoptera (bees, wasps & ants)
