Aphalara monticola
Aphalara monticola is a species of jumping plant louse in the family Aphalaridae, described by Hodkinson in 1973. Like other members of the genus Aphalara, this species is associated with host plants and exhibits the characteristic morphology of psyllids, including membranous wings held roof-like over the body and piercing-sucking mouthparts adapted for feeding on plant sap. The specific epithet 'monticola' suggests an association with mountainous habitats.
Aphalara persicaria
Aphalara persicaria is a species of psyllid (jumping plant louse) in the family Aphalaridae, first described by Caldwell in 1937. The species epithet "persicaria" suggests a possible association with plants in the genus Persicaria (knotweeds), though specific host relationships remain undocumented. It belongs to a genus of small, sap-feeding insects that are poorly studied in North America. Records indicate presence in Cuba and Ohio, USA.
Aphalarinae
Aphalarinae is a subfamily of true bugs in the family Aphalaridae, order Hemiptera. It comprises multiple tribes including Aphalarini, Caillardiini, Colposceniini, Gyropsyllini, and Xenaphalarini, with both extant and extinct genera. The subfamily contains at least 15 extant genera and several fossil taxa. Members are psyllids, a group of sap-feeding insects commonly known as jumping plant lice.
Craspedolepta
Craspedolepta is a genus of psyllids (jumping plant lice) in the family Aphalaridae. Species occur in Europe, Japan, and North America. Several European species have been documented, including C. artemisiae, C. flavipennis, C. malachitica, C. nebulosa, C. nervosa, C. sonchi, and C. subpunctata.

Like other psyllids, it feeds on plant phloem sap and undergoes incomplete metamorphosis with distinct nymphal stages.
Craspedolepta sonchi
A psyllid species in the family Aphalaridae, associated with Sonchus (sow thistle) and related Asteraceae plants. The specific epithet 'sonchi' reflects this documented host relationship. Like other psyllids, it feeds on phloem sap and may induce gall formation on host plants.
Cryptoneossa
Cryptoneossa is a genus of psyllids (jumping plant lice) in the family Aphalaridae, established by Taylor in 1990. Psyllids in this family are small, phloem-feeding hemipterans that often exhibit high host plant specificity. The genus is part of the diverse Psylloidea superfamily, which contains numerous economically significant agricultural pests. Species within Cryptoneossa are associated with specific host plants, though detailed biological information remains limited for many taxa.
Pachypsylla celtidisinteneris
Hackberry Blister Gall Psyllid
A tiny psyllid species that induces blister galls on hackberry leaves. Adults overwinter in concealed locations and emerge in fall, sometimes becoming nuisance pests when they congregate on building exteriors. The species is one of approximately seven hackberry psyllid species in North America, each producing distinct gall morphologies.
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.

hackberry blistergall psyllid
Pachypsylla celtidisvesicula, commonly called the hackberry blistergall psyllid, is a species of aphalarid psyllid native to North America. The nymphs induce distinctive blister-like galls on the leaves of various hackberry species (Celtis spp.), within which they develop through five instars before emerging as adults. Adults strongly resemble the related hackberry nipplegall psyllid (Pachypsylla celtidismamma) but can be distinguished by the gall type their nymphs produce. Like other hackberry psyllids, adults overwinter in concealed locations and can become a temporary nuisance when they aggregate on building exteriors in fall.
Pachypsylla cohabitans
Pachypsylla cohabitans is a species of hackberry psyllid described in 2001. Like other members of the genus Pachypsylla, it induces galls on hackberry trees (Celtis species). The species name 'cohabitans' suggests an association with shared or communal gall structures, distinguishing it from other Pachypsylla species that typically form individual galls. It belongs to the family Aphalaridae, a group of sap-feeding insects commonly known as jumping plant lice.
Pachypsylla pallida
Hairy Bud Gall Psyllid
Pachypsylla pallida is a hackberry psyllid species in the family Aphalaridae, known for inducing distinctive galls on hackberry trees (Celtis spp.). It is one of at least seven species in the genus Pachypsylla that specialize on hackberry hosts. The species produces hairy bud galls, distinguishing it from congeners that create nipple galls or other gall morphologies. Like other psyllids, it has piercing-sucking mouthparts and undergoes incomplete metamorphosis with five nymphal instars developing within the protective gall structure.
Rhinocola
Rhinocola is a genus of psyllids (jumping plant lice) in the family Aphalaridae. The genus was established by Förster in 1848. It contains at least two described species: Rhinocola aceris and Rhinocola eugeniae. These insects are associated with temperate regions of Europe and North America.
Rhinocola aceris
Sycamore psyllid
Rhinocola aceris is a psyllid species in the family Aphalaridae, commonly known as the sycamore psyllid. It is associated with sycamore maple (Acer pseudoplatanus) and related maple species. The species was originally described by Linnaeus in 1758 as Chermes aceris. Like other psyllids, it feeds on plant sap and can cause gall formation on host leaves.
