Winter Larva - Tachinus

Winter Larva - Tachinus
Montpelier, Washington County, Vermont, USA
December 19, 2012
found walking across the snow in a mixed forest near a stream. Outside temp. was a bit under 40 F. In the event that this cannot be ID'd as a larva, I'd welcome any advice/info on rearing it to adulthood.

Moved from Tachyporini.


thanks much, Margaret.
glad i was right about family )))

Moved from ID Request.

nice... suspect one of those winter omaliines
but i'm rather clueless about larvae, and will ask Dr Thayer to take a look, she would know

No, not Omaliinae
Since it has nicely visible two-segmented urogomphi (the projections on the ninth abdominal segment), it's not an omaliine. I think probably something like Tach*inus, but will hedge and say Tachyporini for now. For rearing, I recommend keeping it cool and fairly humid for starters - maybe not quite as cold as refrigerator temperature. For food, if you have no ready source of live/freshly killed insect food, you could try puppy chow - I've heard that many (predaceous) carabid larvae can be reared on that. Al Newton concurred on this, so I'm moving it again. Odd behavior - we haven't really heard of them being winter-active.

very neat!
I'm holding onto it for now, but any advice on rearing? Could it be feeding in winter, or does it just need to be kept in a cool place?

i have no idea
rearing beetles can be an extremely tricky business; survival rates are often all but nonexistent, but i haven't had any experience with staphs
