Black soldier flies are generally considered non-pest flies because they only eat in their larval state (and thus do not transmit disease). They actually tend to reduce the population of pest flies because of their larvae's aggressive feeding habits. The larvae (also called "phoenix worms") are also sometimes used as food for pets or livestock.

I found the larvae of this fly in my worm compost. They fed on wastes put into the compost and did not seem to disturb the worms there. The larvae are no longer visible in the compost. I understand the larvae move to drier places for the next stage of development.
