New data on Urostylis lateralis Walker, 1867 (Heteroptera, Urostylididae) from the south of the Russian Far East

Nymphal Urostylis lateralis Walker, 1867 were reared in cages from eggs that had overwintered in forest under oak rhytidome in the south of Primorsky Krai, Russia. Instar I-II nymphs hatch before the onset of oak's growing season and develop under rhytidome, feeding on the jelly-like coating of egg clutch and molting. As oak leaves unfold, instars III leave their shelters and begin feeding on leaf sap. Adults live in the oak crown. The sequence of molts of all nymphal instars, their feeding, and the timing of seasonal development of the species in nature are documented.
