I checked a little bit in books. May it be Neoitamus? Nikita Vikhrev - Zool Museum of Moscow University |

Not Neoitamus, instead Astochia sp. (correct subfamily -- Asilinae). Lovely specimen, but will probably need a male to ID it further. |

Thank you, Eric! As I understand this genus absent in Russia, even in Far East. Nikita Vikhrev - Zool Museum of Moscow University |

You're welcome Nikita. Astochia is strictly an Old World genus, with about 41 spp. known (Geller-Grimm 1999) -- primarily from the tropical parts of the Oriental Region. Lehr (1988) lists 6 Palaearctic spp, with several known from the former USSR. I don't know any details about the biology of Astochia, but would guess that the long, slender ovipositor is used for egg-laying in tight vegetation. Eric |

Thank you, Eric. 1. I was wrong, Astochia was found in Russian Far East. 2. According Lehr, either Neoitamus and Astocia used the unusually long ovipositor for putting eggs in the tips of broken stems. Nikita Vikhrev - Zool Museum of Moscow University |
