Phylloxera chippokesiensis
Phylloxera chippokesiensis is a gall-forming insect in the Phylloxeridae, closely related to aphids. Like other phylloxerans, it induces abnormal plant growths (galls) on tissues through chemical secretions that redirect plant development. The is named for Chippokes Plantation in Virginia, indicating an association with specific geographic or host plant contexts. As with , it likely has a complex involving parthenogenetic within galls and seasonal transitions between winged and wingless forms.

Identification
No specific diagnostic features for Phylloxera chippokesiensis are documented in available sources. Identification to level in Phylloxera typically requires examination of gall , plant association, and microscopic features of the insect. The species is distinguished from the economically important grape phylloxera (Daktulosphaira vitifoliae, formerly Phylloxera vitifoliae) and pecan phylloxera species (P. devastatrix, P. notabilis) by host plant and gall characteristics.
Habitat
Associated with forested or woodland environments where plants occur. Based on the epithet referencing Chippokes Plantation, likely found in mid-Atlantic coastal plain of Virginia and surrounding regions.
Distribution
Known from Virginia, USA, specifically associated with Chippokes Plantation. Distribution beyond this type locality is not documented in available sources.
Behavior
As with other phylloxerans, induces gall formation on plant tissues through chemical secretions during feeding. The fundatrix (founding female) initiates gall development, after which subsequent develop within the protective gall structure.
Ecological Role
Functions as a gall-forming herbivore that manipulates plant tissue development for shelter and nutrition. Likely serves as a food source for specialized and associated with phylloxeran galls, though specific associates are undocumented.
