A survey of the Agrilus of Wisconsin (Coleoptera: Buprestidae)

Agrilus is the largest genus (117+ species in North America north of Mexico) within Buprestidae and includes several economically significant species; among others, the invasive emerald ash borer. Unfortunately, even baseline knowledge of the species richness and distributions within Wisconsin is minimal. Thus, a survey of the Agrilus of Wisconsin was conducted from 2008 through 2010. Material obtained over the course of two field seasons, in conjunction with the examination of material from various private and institutional collections has included 3,091 specimens representing 52 species, to date. Of this total, 24 species represent new state records, an 86% increase in Agrilus fauna previously known from Wisconsin. For each Wisconsin Agrilus, geographic and temporal distributions are being noted, a specimen-level database is being created, and a key specific to the Wisconsin species with supportive anatomical images is being prepared.
