Asian longhorned beetle
Longhorn Asian beetle: The Asian Longhorned Beetle, or ALB, is an invasive insect that feeds on a wide variety of trees in the United States, eventually killing them. The beetle is native to China and the Korean Peninsula and is in the wood-boring beetle family Cerambycidae. Adult beetles are large, distinctive-looking insects measuring 1 to 1.5 inches in length with long antennae. Their bodies are black with small white spots, and their antennae are banded in black and white.

Damage from the Asian Longhorned beetle might include:
- Dime-sized holes in trees from where beetles crawl out of the wood

August is the best time of year to observe any of these symptoms.
