Not sure that there is enough to go on here, but looks like this male has very wide frons like coloradensis and I did catch a female of that species that I ID'd under the scope earlier in the month.

What's going on here? Are the small red mites babies or parasites??

Maybe Calliphora augur, but the thorax seems too blue.
