This tool is designed to aid in the identification of adult Ironclad and Cylindrical Bark Beetles, a large, worldwide group of diverse, subcortical beetles in the family Zopheridae. This group is thought to include both harmful and beneficial species. Some members (Colobicus, Bitoma, Synchita, etc.) have been associated with particular fungi known to harm or kill valuable hardwood trees, while other members (Colydium, Aulonium, Nematidium, etc.) are thought to be predaceous on the larvae and adults of other destructive, wood-boring beetle pests.

This resource includes an interactive Key to Genera & Species, Genus Fact Sheets, species diagnoses, and hundreds of images to aid in the identification of Ironclad and Cylindrical Bark Beetles found in North America north of Mexico. The interactive identification key runs as a Lucid3 Java Applet. Please read the Lucid3 system requirements for information regarding operating systems, web browsers, and other software needed to run the key.
