Phylloxera chippokesiensis
Phylloxera chippokesiensis is a gall-forming insect in the family Phylloxeridae, closely related to aphids. Like other phylloxerans, it induces abnormal plant growths (galls) on host tissues through chemical secretions that redirect plant development. The species is named for Chippokes Plantation in Virginia, indicating an association with specific geographic or host plant contexts. As with congeners, it likely has a complex life cycle involving parthenogenetic reproduction within galls and seasonal transitions between winged and wingless forms.
Pseudanophthalmus pusio
Ellett Valley Cave Beetle
Pseudanophthalmus pusio is a troglobitic ground beetle endemic to cave systems in the eastern United States. First described by George Henry Horn in 1869, it belongs to a genus of eyeless, pigmentless beetles specialized for subterranean life. The species is known from limited localities in Virginia and represents one of many narrow-range endemics within this genus. Its common name references Ellett Valley in Montgomery County, Virginia, where the type locality is situated.
