Conotrachelus buchanani
Hackberry Curculio
Conotrachelus buchanani is a weevil species in the family Curculionidae, commonly known as the Hackberry Curculio. It is native to North America and has been documented in association with Celtis occidentalis (common hackberry). The species was described by Schoof in 1943. Unlike the well-studied congener C. nenuphar (plum curculio), a major fruit pest, C. buchanani has received limited research attention.

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.
