Locust Borer

Locust borer on leaf
Scientific Name
Megacyllene robiniae
Cerambycidae (longhorned beetles) in the order Coleoptera (beetles)

The locust borer is a longhorned beetle whose larvae tunnel into the trunks of black locust (Robinia pseudoacacia). Their infestations often kill weakened or damaged black locusts. The colorful black and yellow adults are often seen in late summer as they feed on the pollen of goldenrod and other flowers. The black and yellow stripes mimic the color pattern of many stinging insects, which affords this harmless insect some protection from predators.
