Rhyssa
Rhyssa is a genus of large ichneumon wasps in the subfamily Rhyssinae, characterized by exceptionally long ovipositors used to parasitize wood-boring larvae. The genus name derives from Greek meaning "wrinkled." Species in this genus are parasitoids of siricid woodwasps and related wood-boring insects, with females drilling through timber to locate and oviposit on hosts concealed deep within wood. They are distributed across Europe, North Africa, the Near East, North America, the Indomalayan realm, and Australia.
