The paper presents observations on the developmental dynamics of the genus Urostylis Westwood, 1837 in the natural conditions of the southern Primorsky Krai, Russia. The aim of the study is to show the developmental features of Urostylis trullata Kerzhner, 1966 and provide a comparative analysis of the duration of ontogenesis of three species: U. trullata, U. annulicornis Scott, 1874 and U. lateralis Walker, 1867. Nymphs of U. trullata from eggs that had overwintered in Quercus mongolica Fisch. ex Ledeb. under rhytidome were reared in cages. Instar I–II nymphs hatch before the onset of oak’s growing season and develop under rhytidome, feeding on the jelly-like coat of the egg clutch and molting. As Mongolian oak leaves unfold, instars III nymphs their shelters and begin feeding on leaf sap. The postembryonic phase in all three species lasts, on average, 65–68 days. However, observations on U. annulicornis and U. trullata have shown their ability to complete postembryonic development for minimal periods of 54 and 58 days, respectively.
