This colorful beetle (Megacyllene robiniae) is very destructive to locust trees in its larval stage; but since Pittsburgh has an infinite supply of locust trees, we need not worry about it. Probably these creatures are the only things that keep the locust trees from taking over and imposing martial law. The adult beetle looks very dashing in its striped livery. It eats goldenrod pollen, which means that our Locust Borers are very happy right now.
