Dance flies are common, in general, in this area. They are commonly seen flying in small swarms and are rarely seen sitting. The swarms are generally for mating. Male flies may capture an insect and wrap it in silk and offer it to females in the mating swarm. The males fly up and down in a sort of dance. Females are presumed to mate with a male based on the food gift.

Dance flies are found worldwide with an estimated 3,000 species in 30 genera. There are more than 760 species of dance flies in North America, most of them not yet described. This fly was photographed in early July when it came to lights set up to attract moths at Neale Woods.
