The adult fly is primarily black with a yellow face and thin white stripes on the abdomen. It is commonly found along the east coast of the United States and is often found near flowering plants. ''P. tibialis'' flies parasitize many different species of bees by laying their eggs inside the abdomen of their host.

The host then dies and the larva envelopes itself in a puparium and pupates inside of the corpse. After an extended period of pupation, the adult emerges from the corpse of the host bee.
