Boredom and cold knowledge:

The name of the black flying insect is the moth Simulium, and the English name is drain fly. Although it looks a little like a moth, it is actually a relative of a diptera, a fly mosquito. When you see one in the bathroom at home, it means that there are many other larvae (like hairy maggots) twisting under the sink, drain hole, sink or toilet lid.
