Pachypsylla celtidisvesicula, commonly called the hackberry blistergall psyllid, is a species of aphalarid psyllid found in North America. The nymphs of this species induce blister-like galls on the leaves of various hackberries (Celtis spp.) throughout its range.^[1]

It closely related to the more common hackberry nipplegall psyllid (Pachypsylla celtidismamma), which it strongly resembles as an adult.^[1]
