Abstract

Overwintering egg cases of two praying mantises, Tenodera aridifolia and T. angustipennis, were collected in southern Osaka Prefecture after their hatching season in early summer, and reared under quasi-natural conditions. Adults of Thaumaglossa hilleri emerged from 5 and 2 out of 10 egg cases of respective T. aridifolia and T. angustipennis in the autumn, and these were considered as the 1st generation. Thus, Th. hilleri is assumed to be bivoltine ; larvae of the 1st generation feed on hatched egg cases of praying mantises and develop into adults in the autumn, while those of the overwintering generation feed on overwintering egg cases and emerge in the spring. Since adults of Th. rufocapillata were observed to have emerged together with the congeneric Th. hilleri from a single egg case of T. aridifolia, these two species of the dermestids may be competitive in larval stage from the 1st generation.
