About Asian Longhorned Beetle
The Asian longhorned beetle (Anoplophora glabripennis) is a striking 20–35 mm beetle with a glossy black body dotted in white and antennae longer than its body. Larvae bore into the heartwood of maples, elms, horse chestnuts, poplars, and willows, causing irreparable girdling that kills the tree. Infested trees show circular exit holes roughly 12 mm across, oozing sap, and accumulations of coarse sawdust-like frass at the base. Eradication programs in the United States have required felling and chipping thousands of trees to prevent its spread. It poses a catastrophic risk to North American urban forests and hardwood industries.
