Locust borer

Locust borer

Jeff Hahn

Size: 3/4 inch long

Where/When: Most commonly found indoors during winter, although can be found at other times of the year.

Significance: Is associated with black locust wood. Can be brought indoors with firewood or lumber in construction projects. Is harmless to people. Can cause cosmetic damage to wood from which it emerges, but fortunately it does not re-infest wood.
