Photo#742179
Braconidae on Anthomyiidae, parasitoid wasp

Braconidae on Anthomyiidae, parasitoid wasp
100 Acre Wood, Winneshiek County, Iowa, USA
Size: 4.7 mm
Wasp emerged July 15, 2012. Picture taken July 30
Long term question: Data entry: Date taken, (I assume means the photo.) Only specify for wild specimens (which wouldn't exactly be reared specimens) Photo dates don't necessary match with emergence dates. So for BG Data purposes it probably would be best to use the emergent date rather than the photo date. I'd like confirmation of this from an editor, please.

Date
When I photograph live reared specimens that haven't been artificially kept away from seasonal temperature changes, I use the date that the photo was taken, and indicate the emergence date in the notes if it was substantially different. For dead specimens, and for specimens that I have reason to believe emerged an an unnatural time, I leave the date blank and indicate the emergence date (or date I discovered the dead adult) in the notes. If you know when it emerged but then killed it and photographed it later, it seems reasonable to enter the emergence date in the data field, but under no circumstances should you put the photo date in the data field for dead specimens photographed long after they died.

The host is a Chirosia (Anthomyiidae) that has never been reared (or documented in any literature as far as I know). The larvae burrow in soil and overwinter before emerging as adults. I have several in my refrigerator, waiting for spring.
