Insects Frequently Confused with Emerald Ash Borer in North Dakota (E-1604)

The Emerald ash borer is a beetle (Order Coleoptera). Beetles are recognized by having shell-like front wings called elytra. When the wings are folded, they meet forming a median line down the back. Currently, Emerald ash borer has not been found in North Dakota.
