Looks like a Eurithia sp. ... is it male and did you hook-out the genitalia?

Genitalia  noup  I didn't know I should do that. Well, at the moment I would have no time to do that either. So very many flies to handle every day. I have just time to take some pictures of something that is somehow interesting or new for me. When the winter comes it will be time for genitalia work Jari |

Eurithia sp. don't *need* male genitalia (they usually have other good-enough features) but the male genitalia are so distinctive that it can save you a lot of hassle  With male Eurithia all you have to do is to hook out the extremely large genital capsule so that the external genitalia are fully visible - nothing complicated. It is best done when the fly is soft and pliable because, like sarcophagids, the genitalia become pretty rigid once dry. As an aside, this is one reason that I micro-pin everything on its side onto flat foam sheets in plastic boxes. This allows me to hook-out any genitalia and pin them open while the fly dries. When I am ready to identify them I move the specimen to a foam stage-mount and it is ready to manipulate and curate As a general rule I hook-out *all* male genitalia on every fly I catch. You never know when they will be useful but they usually are at some point and it's better to have done them while the fly is "cooperative" than when it is pinned and a few years old Anyway, never mind - send it to me in the winter (with any tachs) and I will "butcher" it for you

Thank's again. Shall I name it cf anthophila so far and rename it after the specimen is determined ? Jari |
