Fly

Flies are an order of winged insects that survived the Great War.

Background
Common flies weathered the apocalypse and came out seemingly unmutated. Their ecological niche remains unaltered as well: people view flies as little more than pests or vectors for disease, but they serve a vital role in the consumption of detritus. Much to the irritation of ghouls, this means that flies feed on the nutrients of their rotting bodies.

Appearances
Flies appear Fallout 2 and are mentioned in Fallout 3 and Fallout: New Vegas.
