Locust Plant Bugs are tiny, green, flying insects that are an annoyance to homeowners. First, they ruin the appearance of a Locust tree by causing severe defoliation. Secondly, homeowners who stand or sit beneath these trees, especially on breezy days, realize these flying insects are all over them. This tree pest likes to be protected, so it will find its way under clothing, and even onto our scalps, which causes severe itching! Thirdly, they cause severe sap dripping all over vehicles, decks, patios, our children’s toys, and lawn furniture.
The Locust Plant Bug is an early spring/summer insect. The populations can be much heavier in some years than others, but they are always present to some degree.
Some years, Locust trees will fully foliate, and then defoliate as the insect ‘goes to work’ feeding on the leaves. In other years, the insects hatch early and attack the leaf buds themselves, preventing the tree from foliating at all until sometime in June!
