Pachypsylla celtidisumbilicus
Hackberry Disc Gall Psyllid
Pachypsylla celtidisumbilicus is a species of hackberry psyllid that produces distinctive disc-shaped galls on hackberry leaves (Celtis spp.). Adults emerge in fall and seek shelter to overwinter, often becoming household nuisances when they congregate on building exteriors. The species is one of at least seven Pachypsylla species associated with hackberry in North America, each producing a characteristic gall morphology.
