Inquiline Hackberry Leaf Gall Psyllid
Pachypsylla cohabitans
This record describes Pachypsylla cohabitans (species). Recorded family: Carsidaridae. Recorded order: Hemiptera.
Identification and Appearance
Morphologically extremely similar to leaf-galling Pachypsylla . Adult females can be distinguished by their green (as opposed to dark brown) abdomen, and males may be be distinguished on the basis of the shape of the paramere (apex of paramere obtusely angled in cohabitans , smoothly rounded in celtidismamma , and sharply angled (nearly 90°) in celtidisasterisca ). Late instar nymphs have yellow (as opposed to brown) wingpads .

Habitat and Range
Geographic Range
Widespread east of the Rockies
Diet and Behavior
Diet: Hackberry (Ulmaceae: Celtis )
Life History
Unlike all other Pachypsylla , P. cohabitans is unable to produce its own galls. Instead, it becomes incorporated in the galls of other leaf-galling species during gall initiation. The inquiline becomes confined to side cells within the gall whereas the true gall former may be found in the center cell .

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Pachypsylla cohabitans. Species-specific details appear above.
Group overview
Hemiptera (true bugs) includes over 80,000 described species across cicadas, aphids, leafhoppers, shield bugs, and bed bugs. Aphids alone cost global agriculture an estimated $2.5 billion annually in crop losses.
Ecological role of the group
Many Hemiptera are essential food sources for birds and predatory insects. Cicadas provide massive nutrient pulses during emergence events - a single Brood X emergence can involve trillions of individuals across 15 states.
Economic and practical significance of the group
The brown marmorated stink bug (Halyomorpha halys) caused $37 million in apple crop losses in a single year in the U.S. Mid-Atlantic region. Bed bug infestations in the U.S. increased by 500% between 2001-2010, costing the hotel industry hundreds of millions annually.
