23 April 2008, NB, Canada. Length 7mm.

I posted an image of what appears to be this same species on 25 April 2007.
Both Andrzej and Kahis ID'd it as a Scathophagidae. It was a poor image, so I deleted it am replacing it with this one (not a policy I would recommend:p)

Is this the same species as SEE HERE but just sexual dimorphism?

Both males, so not sexual dimorphism (but watch out for intersexes in Scathophaga - where castrated males take on the secondary sexual characters of the females!)

Thanks. Glad to have a 2nd species. This one is far less common than the larger yellow one.
Castrated males; yikes, bad enough separating males from females let alone intersexes:o

Did you decide not to send any mounted Ephydra?
