Beetle banks, linear strips of perennial native bunch grasses usually planted on a berm within or adjacent to fields, are a tool to support biological pest control on farms that promote movement of beneficial insects into the crops. The grasses provide overwintering shelter for a diversity of predatory invertebrates, especially ground beetles that contribute to the suppression of crop pests such as aphids, slugs, snails, caterpillars, and the larvae of herbivorous beetles like Colorado potato beetles. This guide will help farmers and land managers with planning beetle bank installations in the Upper Midwest Region.
