Tachinid?? - Coenosia

Tachinid?? - Coenosia
Aromas, San Benito County, California, USA
October 15, 2007
Size: ~5mm.
Yet another fly from our potato plants near the compost bin(live oak/chaparral habitat). Perhaps a tachinid?

Moved from Tiger Flies.

Moved from Muscoidea.

I think
this might actually be a muscid. Tachinids have spikier hair. Phenomenal photo!

I think
I'm starting to figure this out. First off, I'm totally in accord with Graham. Gary, in looking at this and two other of your recent fly posts, I noticed that this one has prominent calypters, those large whitish panels on the sides. That's a mark of Calyptratae flies, a catgory that includes both tachinids and muscids.

Not so with the two other posts, which I believe are Acalyptratae. (If there's a fly expert out there, please confirm or sound a loud raspberry!)

Coenosia spp maybe??
I'm glad you're figuring these flies out, Ron. Now, you just have to start giving me lessons!

Thought I just did. LOL!
Well, if you're going to force me to learn, you'll have to do it too.

Coenosia looks good to me, but I have a spotty record with them. Generally, I see them perched on reeds by water, wating to dart off and swoop down on smaller insects, typically flies. As a result, behavior plays a part in my IDs of them. Does any of this sound familiar?

Tiger/Hunter flies
I my neck of the woods (ie my front yard), they tend to light on leaves at about waist to head height and wait for me to kick up the leafhoppers as I go traipsing about taking pictures. I've gotten a couple decent pics of Hunter flies dining on leafhoppers.

Coenosia certainly looks plausible
Looks very much like this guy Coenosia humilis. Thanks Kevin.
