Crown Wasps by melvynyeo Crown Wasps by melvynyeo
A Crown wasp laying eggs by drilling her ovipositor into the bark until it reaches the host (beetle larva?) and injects an egg through the hollow tube into the body cavity.

Stephanidae, sometimes called crown wasps, is a family of Parasitoid wasps placed in the superfamily Stephanoidea, which has eleven living genera and at least 345 living species. The family is considered cosmopolitan in distribution, with the highest species concentrations in subtropical and moderate climate zones. Stephanidae also contains four extinct genera described from both compression fossils and inclusions in amber.

All genera of Stephanidae have a pronotum that is modified to some extent. They bear highly modified hind legs, with a swollen hind femora that has large teeth on the underside, and the tibias have a tip end that widens distinctly. The largest species, reaching up to 35 millimetres (1.4 in) in length, are found in the genus Megischus. Stephanids are noted as parasitoids of xylophagous beetle larvae, with a majority of the stephanids coming from the families Cerambycidae and Buprestidae, though some Curculionidae and occasional hymenopteran hosts are taken. One species, Schlettererius cinctipes, is a known parasitoid of horntail wasps, and has been introduced to Tasmania as a biological pest control agent.
