Flesh Fly
There are over 300 species of flesh flies in the U. S. & Canada. The common name comes from the fact that their larvae is laid in and often develops in decaying animal flesh. Flesh flies are of a human health concern for the possible transmission of disease organisms. The adults range from 1/4" to 5/8" long, usually light gray in color, with 3 black stripes along their body and they have large reddish eyes.

Females will give birth to larvae instead of laying eggs; with the larvae being laid on a potential food source such as decaying animal flesh, spoiled meat, food waste or animal excrement. The mature larvae eventually leave the breeding source in search of a drier place in which to pupate. The life cycle from adult to adult, can vary with species, usually ranging from 8 to 36 days.

These flies are attracted to potential food sources & larvae developmental areas that have had prolonged exposure to sunlight. Adults can be found in a variety of areas such as on flowers & plants, on other insects or invertebrates, on live or dead rodents or other animals, garbage, etc… They prefer stone walls as resting places and show the greatest activity at temperatures of 76 to 82 degrees F. Within buildings dead birds or rodents can be a potential food source for these flies.
