Leptoglossus
leaf-footed bugs
Leptoglossus is a genus of true bugs in the leaf-footed bug family Coreidae, tribe Anisoscelini. Species are characterized by leaflike dilations of the hind tibia, a diagnostic trait of the genus. The genus is distributed throughout the Americas, with some introduced populations in Europe and Asia. Several species are economically significant agricultural pests, notably L. occidentalis, which has become invasive in multiple continents.

Phylloxera auburnensis
Phylloxera auburnensis is a gall-forming insect in the family Phylloxeridae, closely related to aphids. Like other phylloxerans, it induces abnormal plant growths (galls) on its host through chemical secretions that manipulate plant tissue development. The species is part of a genus containing several economically significant pests, including grape phylloxera (Daktulosphaira vitifoliae, formerly Phylloxera vitifoliae) and pecan phylloxera species. Specific details about P. auburnensis hosts and distribution remain limited in available literature.

Phylloxera bispinae
Phylloxera bispinae is a gall-forming insect in the family Phylloxeridae, closely related to aphids. Like other phylloxerans, it induces abnormal plant growths (galls) on host plants through chemical secretions that manipulate plant tissue development. The species overwinters as eggs and has a complex life cycle involving multiple generations and winged dispersal forms. Specific host associations and detailed biology for this species remain poorly documented compared to economically important relatives such as the grape phylloxera (Daktulosphaira vitifoliae) and pecan phylloxera species.

Phylloxera caryaefoliae
pecan leaf phylloxera
Phylloxera caryaefoliae is a tiny, soft-bodied, gall-forming insect closely related to aphids that infests pecan trees. It produces conspicuous galls exclusively on leaf tissue, distinguishing it from the more damaging pecan phylloxera (P. devastatrix) which attacks shoots and nuts. While extensive infestations may cause some defoliation, this species is generally less economically significant than shoot-attacking phylloxerans. The insect has a complex life cycle involving multiple generations and both winged and wingless forms.

Phylloxera castaneae
Phylloxera castaneae is a gall-forming insect in the family Phylloxeridae, closely related to aphids. The species induces abnormal plant growths (galls) on its host plants through chemical secretions that manipulate plant tissue development. Like other phylloxerans, it has a complex life cycle involving multiple generations and both parthenogenetic and sexual reproduction. The species name indicates an association with Castanea (chestnut) hosts, though specific details about its biology remain poorly documented in available literature.

Phylloxera flavoconica
Phylloxera flavoconica is a species of phylloxeran, a tiny sap-sucking insect in the family Phylloxeridae. Phylloxerans are closely related to aphids and are known for inducing gall formation on host plants. The genus Phylloxera includes species that are significant agricultural pests, most notably the grape phylloxera (Daktulosphaira vitifoliae), though the specific impacts of P. flavoconica are not well documented in available sources.

Phylloxera georgiana
Phylloxera georgiana is a gall-forming insect in the family Phylloxeridae, closely related to aphids. Like other phylloxerans, this species induces abnormal plant growths (galls) on its host plant through chemical secretions that manipulate plant development. The species was described by Pergande in 1904. Very few specific details about its biology, host associations, or distribution have been documented in the available literature.

Phylloxera glabra
Phylloxera glabra is a species of phylloxeran, a group of small, soft-bodied insects closely related to aphids within the family Phylloxeridae. Like other phylloxerans, this species induces gall formation on host plants through chemical secretions that manipulate plant tissue development. The species was described by von Heyden in 1837 and has been recorded from parts of Europe including Belgium, Denmark, and Norway. Phylloxerans exhibit complex life cycles involving multiple generations and both sexual and parthenogenetic reproduction.

Phylloxera intermedia
Phylloxera intermedia is a species of phylloxeran, a group of tiny, soft-bodied insects closely related to aphids. Like other phylloxerans, it induces gall formation on host plants through chemical secretions that manipulate plant tissue development. The species was described by Pergande in 1904. Specific details about its host associations and biology are limited in available literature, though phylloxerans generally have complex life cycles involving both sexual and parthenogenetic generations.

Phylloxera pilosula is a gall-forming insect in the family Phylloxeridae, closely related to aphids. Like other phylloxerans, it induces abnormal plant growths (galls) on its host plants through chemical secretions that manipulate plant tissue development. The species was described by Pergande in 1904. Specific host associations and detailed biology for this particular species remain poorly documented in available literature.

Phylloxera rileyi
Phylloxera rileyi is a gall-forming insect in the family Phylloxeridae, closely related to aphids. The species is known from limited observations and taxonomic records, with only two documented observations on iNaturalist. Like other phylloxerans, it likely induces abnormal plant growths (galls) on host plants through chemical secretions that manipulate plant development. The species was described by Riley in 1874.

Phylloxera stanfordiana
Phylloxera stanfordiana is a species of phylloxeran insect in the family Phylloxeridae, order Hemiptera. It is closely related to aphids and shares their soft-bodied morphology and plant-feeding habits. The species was described by Ferris in 1919. Like other phylloxerans, it is known to induce gall formation on host plants through its feeding activity. The specific epithet 'stanfordiana' refers to Stanford University, where the type specimen was collected in 1904.

Phylloxera texana
Phylloxera texana is a species of gall-inducing insect in the family Phylloxeridae, described by Stoetzel in 1981. Like other phylloxerans, it is closely related to aphids and induces abnormal plant growths (galls) on its host plants through chemical secretions that manipulate plant tissue development. The species is presumably associated with pecan or related hickory species given its genus affiliation and geographic name, though specific host records and detailed biology remain poorly documented in available literature.

Phylloxera wiedenmanni
Phylloxera wiedenmanni is a gall-forming phylloxeran that induces galls on hickory trees. As a member of the family Phylloxeridae, it is closely related to aphids and shares their piercing-sucking mouthpart morphology. The species overwinters as eggs deposited on bark or near old galls, with nymphs emerging during bud break to feed on new leaf tissue. Its feeding stimulates the formation of globular galls on leaves and petioles, within which the insect completes development. The species exhibits complex life history traits including parthenogenetic reproduction within galls and winged dispersal forms.
