I am not an entomologist, but....
I think it might be a bibionid, a march fly. Some of them have some
Color black, sometimes shiny black, often with a pubescence all over.

> Dear All,
> Especially to entomologists on the list. I know next to nothing
about mating displays in flies, but a gnat (ca. 4 mm. long) crawling on my
door window caught my eye. It seemed to be displaying in a way that is
reminiscent of male jumping spiders trying to attract a female. However,
the appendages being raised by this gnat seem to be the third (posterior)
pair of legs thrust upwards and arching somewhat forward towards the head.
After putting the gnat in a vial, it continued doing this, so I thought
perhaps it might be a threat posture as well.

certain male gnats usually do, and if so, to what family of gnats might it
