Musca domestica, house flies. They never bothered me in particular, until I became an insectary technician- growing flies. Yes, I was lord of the flies, daddy to 5 to 9 million maggots in process per day. The breeding room was not a sight for the timid, not to mention the visual effect of millions of maggots squirming around in a room.
Why cultivate flies? Because the maggots are a food source for small predatory wasps. The wasps are cultivated as an Integrated Pest Management means of fly control around stables and other fly breeding habitats. Shipped out 5 days before hatching, the parasite infected fly pupae hatch out a new batch of wasps which immediately seek mates and new maggots in which to lay their eggs, effectively limiting new fly populations.
Anyway, after holding this most interesting of jobs for a year or so, I began to really despise flies, and this hold true to this day. Go figure.
