Pest description and damage The adult shothole borer is a brownish-black beetle about 0.08 inch long. The larvae are white, legless, and about 0.16 inch long. When the numerous beetles emerge, the bark takes on a shothole appearance. These beetles are primarily a problem on injured or stressed plants, but healthy trees growing adjacent to blocks of neglected trees are attacked.
