A "one-stop shop" for wasp identity information

August 20, 2015 by Jan Suszkiw

Determining the identity of parasitic wasps—some measuring less than a millimeter long—can be a time-consuming process that includes comparing their features to descriptions in published works and disparate specimen collections. Now, the same task could begin with the click of a mouse, thanks to an international team of researchers, including one from the U.S. Department of Agriculture (USDA).

The team has published a new online document that consolidates the latest information on the wasp superfamily Cynipoidea. The monograph uses pairs of interactive, image-based identification keys—including those of wing shape, body segmentation and other characteristics—to help users navigate to the correct genus or species of the wasp of interest, along with available biological, geographic and other information about the insect, including locations of existing specimens.

Cynipoid wasps are critical components of natural and agricultural ecosystems, attacking the larval stages of pest flies, such as leaf-mining flies and fruit flies, according to Matt Buffington, a team member and entomologist at the USDA Agricultural Research Service's (ARS) Systematic Entomology Laboratory in Washington, DC.
