Minnesota Insects


Order Diptera

Diptera is the order of insects that is characterized as having a single pair of functional wings on the mesothorax and a pair of halteres, reduced, knob-like structures derived from the hind wings, on the metathorax. The order includes true flies, mosquitos, gnats, and midges.

There are about 120,000 described species worldwide, though there are thought to be twice that number of species currently living.

Hunchback bee fly

This is a medium-sized bee fly with a distinctly hunch-backed appearance. It is fairly common and widespread in eastern North America. It’s unusual shape mimics the robber fly. The larvae are kleptoparasitic, eating the collected food in the nests of solitary wasps, and possibly also parasitic, eating the larvae in the host’s nest.

Capitalization of Common Names

Insect scientific names are governed by the International Commission on Zoological Nomenclature (ICZN). Vernacular (common) names are not. In an attempt to “assure the uniformity of (common) names of common insects” the Entomological Society of America (ESA) published Common Names of Insects and Related Organisms. ESA has no rule or guideline that addresses capitalization of common names. However, the database of common names published by ESA does not capitalize common names. National Center for Biotechnology Information (NCBI) also uses uncapitalized common names. Most other sources, including ITIS, BAMONA, Odonata Central, and the Peterson Field Guides, capitalize common insect names. MinnesotaSeasons.com will adhere to the convention followed by ESA and NCBI.
