Meromacrus acutus - male

Meromacrus acutus - Male
Parkwood, Durham County, North Carolina, USA
June 21, 2007
Size: 18 mm
This fly appeared to be ovipositing repeatedly in a bucket of compost, but see comments--perhaps it was not doing so. Size estimated.

(Yes, comparing other images for this species on BugGuide, this must be a male.)

The touching eyes
are suggestive of a male!

Good point!
Well, maybe it was just dipping its abdomen for some reason on the compost--sure looked like ovipositing--but I did not see any eggs, so point well taken.

I'll turn off the M/F marker for now. Looking at our images here, we do seem to have some with the larger eyes (males?) and some with eyes that do not touch (presumed females).

I have seen many syrphids bob the abdomen up and down, which I suspect is part of the mimicry-reinforcement behavior, as many wasps have twitchy behinds as well:-)
