Neophyllura bicolor
Neophyllura bicolor is a species of psyllid (family Liviidae) described by Martin in 1931. It belongs to the superfamily Psylloidea, a group of small plant-feeding insects commonly known as jumping plant lice. The species epithet 'bicolor' suggests a two-toned color pattern. Records indicate it has been observed in California (CALOO).
Neophyllura pruinosa
Neophyllura pruinosa is a species of jumping plant louse (psyllid) in the family Liviidae, first described by Martin in 1931. As a member of the Hemiptera order, it is a sap-feeding insect that likely specializes on particular host plants. The genus Neophyllura is part of a group of psyllids associated with various plant families, though specific ecological details for this species remain poorly documented in available literature. The species has been recorded in California, USA based on distribution data.
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.
Pachypsyllinae
Pachypsyllinae is a subfamily of jumping plant lice (psyllids) in the family Aphalaridae. It comprises three genera: Celtisaspis, Pachypsylla, and Tetragonocephala. Members of this subfamily are associated with hackberry trees (Celtis species) as their host plants. The group was previously classified in the family Carsidaridae, but recent revisions have placed it in Aphalaridae. The genus Pachypsylla includes species that form distinctive plant galls on hackberry leaves and stems.
Pexopsylla cercocarpi
Pexopsylla cercocarpi is a species of jumping plant louse (family Psyllidae) described by Jensen in 1957. The specific epithet "cercocarpi" indicates an association with Cercocarpus (mountain mahogany), a genus of flowering plants in the family Rosaceae. Like other psyllids, this species is likely a phloem-feeding specialist on its host plant. The genus Pexopsylla is part of the diverse psyllid fauna of western North America.
Psylla betulaenanae
Psylla betulaenanae is a species of psyllid (jumping plant louse) in the family Psyllidae, described by Ossiannilsson in 1970. It belongs to a genus of phloem-feeding insects associated with woody plants. Like other psyllids, it has piercing-sucking mouthparts adapted for feeding on plant sap. The species epithet suggests an association with birch (Betula), though specific host plant relationships require confirmation from original taxonomic descriptions.
Psylla floccosa
Psylla floccosa is a species of jumping plant louse in the family Psyllidae, first described by Edith Marion Patch in 1909. Like other psyllids, it is a small phloem-feeding insect that uses piercing-sucking mouthparts to extract plant sap. The species is part of the diverse genus Psylla, which contains numerous species associated with various host plants. Specific ecological and biological details for P. floccosa remain poorly documented in the scientific literature.
Purshivora
Purshivora is a genus of psyllids (jumping plant lice) in the family Psyllidae, established by Heslop-Harrison in 1961. Members of this genus are small sap-sucking insects associated with host plants. The genus is placed within the suborder Sternorrhyncha, a group of Hemiptera characterized by piercing-sucking mouthparts and often complex plant associations. Specific biological details for Purshivora remain poorly documented in accessible literature.
Purshivora aculeata
Purshivora aculeata is a species of jumping plant louse (psyllid) in the family Psyllidae. As a member of Sternorrhyncha, it possesses piercing-sucking mouthparts adapted for feeding on plant vascular fluids. The genus Purshivora comprises psyllids associated with host plants in the genus Purshia (bitterbrush), suggesting a specialized plant-insect relationship. Limited observational records exist for this species.
Purshivora nigranervosa
Purshivora nigranervosa is a species of jumping plant louse in the family Psyllidae. The genus Purshivora comprises psyllids associated with plants in the genus Purshia (bitterbrush), suggesting a specialized host relationship. Very few observations of this species exist in scientific databases.
Spanioneura
Spanioneura is a genus of psyllids (jumping plant-lice) established by Arnold Förster in 1848. Species are primarily European in distribution, though the type species S. fonscolombii has been accidentally introduced to the United States. The genus comprises at least five described species, with S. fonscolombii being the most widely studied due to its economic significance as a pest of boxwood (Buxus species).
Trioza magnoliae
Red Bay Psyllid
Trioza magnoliae, commonly known as the Red Bay Psyllid, is a gall-forming psyllid native to eastern North America. This species induces characteristic galls on the leaves of native Persea bay trees, particularly red bay (Persea borbonia) and related species. The insect has a wide distribution across the eastern and central United States. While primarily an ecological curiosity due to its gall-forming habit, it has gained attention in relation to the decline of red bay populations caused by the invasive laurel wilt disease, as the psyllid's host trees face significant mortality.
