Hackberry Nipple Gall Psyllid
Pachypsylla spp. (Hemiptera: Psyllidae)
Small jumping insects that create distinctive nipple-shaped galls on hackberry leaves. Adults emerge in fall and become household nuisances when seeking winter shelter. The insects resemble miniature cicadas and do not cause serious harm to host trees.

Adults emerge from galls in September and seek protected winter shelter. They are attracted to light-colored houses and lights at night. Adults are small enough to pass through window screens. After winter dormancy, they become active in spring and exit structures to reproduce on hackberry trees.
