Looks quite like an ichneumon wasp.

Possibly same as...
Resembles this one from Washington; yours might be the female.

they certainly do look similar. Thanks John.


Typically I would agree with your ID except for one problem - where are the halteres if it is a fly? Could they be there and I'm just not seeing them? The wings (need four if a wasp) do not look typical of an ichneumon in any event, even though the rest of the body certainly might. The resting position is also very un-ichneumon-like. It seems clear that there are only two wings in this image.

I did the same thing
first I thought wasp, couldn't match it and then resorted to my field guides. Then I found this fly, and couldn't see any halteres in any of my pics. I chalked it up to they must be hidden. It certainly flies more like a gnat than a wasp as well.

Hidden halteres.
They 'are' hidden. Stalked, and the part usually visible is obscured by light reflecting off the wings. Moving this to the family page for now.

Thanks Eric.

Lynette, can you provide an approximate size?

approximately 10 mm.
