Cluster Fly

This species is widely distributed throughout the United States. Adult cluster flies resemble house flies, but are slightly larger, about 5/16 inch long, narrower and nonmetallic. Adult Cluster flies lay there eggs in the soil near earth worms. About three days later the eggs hatch and the larva enters the earthworm hosts. After 13-20 days the larva leaves the bodies of the host and begin pupation. After the larva pupates in the soil the adult fly emerges and begins to feed on nectar, and juices of fruits. The cluster fly adult will enter homes in an attempt to ride out the winter typically found in most attics.
