Pachypsylla is a genus of psyllids.[1] Each of its four species lay eggs on the leaves of the Celtis occidentalis tree. Upon hatching, the young psyllids become encased in a "gall" which the young leaf parts grow in response to the infestation.[2] Species of Pachypsylla include Pachypsylla celtidisgemma (hackberry bud gall maker), Pachypsylla celtidismamma (hackberry nipplegall maker), Pachypsylla celtidisvesiculum (hackberry blistergall psyllid) and Pachypsylla venusta (petiolegall psyllid).
