Aquatic Hymenoptera (Wasps) of Michigan

Introduction

A number of parasitic wasps (parasitoids) have come adapted for aquatic existence by attacking various life stages (principally eggs, larvae and/or pupae) of aquatic insect groups, especially those of Heteroptera and holometabolous orders (e.g., Lepidoptera, Coleoptera, etc.).

Genera are denoted in green; species denoted in bold blue have been recorded in Michigan; other species denoted in black bold are likely to occur based on their known distribution. You can use the Find function in your web browser to locate families, genera, and species. Synonomous species (indented) are listed below the current valid species (denoted in bold) with its taxonomic status indicated.

Information regarding the occurrence of aquatic Hymenoptera in Michigan is currently in preparation. Please email the author if you have records or information regarding this group in Michigan. Below is a list of genera parasitize aquatic insects found in Michigan. It is adapted from Bennett (2007, second printing), and with surveying of deposited collection material. Additional information is from Cebulski and O'Brien (2013).
