I was setting up to shoot the beetle, Pharaxonotha kirschii, when this midge happened on the scene. Chironomidae, but is it Cricotopus?

What's that on your profile picture? Are those two mites on a midge?

Yes, two mites on a midge.

I have various observations I've identified as Cricotopus, most recently this one.

Also this one.

These all seem similar, but I see some differences. Are the differences enough to indicate different species? A couple others are clearly different, and I don't recall why I identified them as Cricotopus. I'm thinking now I may be wrong. Example:

I'm doubting my ID because it's all black. It seems like there's at least some light color banding in Cricotopus. Or are there solid black ones?

The black and yellow midges are Cricotopus. I don't know about the black one. Some Cricotopus are black and can not be identified by color.
