Longhorn Locust Borer

Megacyllene robiniae

Description:

Female, 15 mm in length. Yellow and black stripes. Long antennae.

Habitat:

Eastern North America. Adults found feeding on goldenrod plants as seen here. Female locust borer beetles fly to the trunk of black locust trees and lay eggs in crevices in the bark. These eggs hatch into larvae called locust borers that tunnel beneath the bark of the tree, destroying vascular and structural tissues beneath.

Notes:

The yellow and black colouration and markings mimics stinging insects and probably helps protect the beetle against predators.
