Thaumaglossa

Hatched egg cases of praying mantises; specifically documented from Tenodera aridifolia and T. angustipennis egg cases in southern Osaka, Japan. Occupies the vacant cavity within hatched oothecae.

Japan (southern Osaka documented for T. rufocapillata); broader geographic range for the genus unconfirmed in available sources.

Adults emerge August to October for first generation; overwintering generation adults observed in spring and autumn. Bivoltine pattern with generation-specific timing.

Bivoltine: overwintering generation with larvae in overwintering mantis egg cases, and first generation with adults emerging August to October from hatched summer egg cases. Multiple adults (mean 5.5-9.1, up to observed range) emerge from single egg case with 1:1 sex ratio. First generation emergence rates (56.3-70.0%) substantially exceed overwintering generation rates.

Aggregated emergence from single host egg cases; first generation shows markedly higher emergence success than overwintering generation.

Specialist utilizer of post-hatching mantis egg case cavities; occupies vacant niche after mantis nymphs exit. Subject to parasitism by bethylid wasp Laelius sp.

• Other DermestidaeThaumaglossa distinguished by specialized association with mantis egg cases; most dermestids are generalist scavengers or feed on dried animal products, pollen, or other substrates rather than oothecal specialists.
