Phylloxera crypta
Phylloxera crypta is a gall-forming insect closely related to aphids, known to induce distinctive galls on hickory trees (Carya ). Like other phylloxerans, this species manipulates plant tissue development through chemical secretions during feeding, creating protective structures that house developing nymphs. The species exhibits a complex involving multiple and both sexual and parthenogenetic phases.
