Fly

Flies are winged insects known to live in New California, and areas in New California's vicinity. It is also possible to encounter flies in the Commonwealth.

Characteristics
Unlike bloatflies and various other insects, these flies have remained apparently untainted by the nuclear fallout of the Great War, retaining their pre-War size at the very least. Populations of these insects can be found in various wastelands most commonly around decaying organic matter, such as dead bodies (including those of bloatflies) or feces.

Appearances
Flies appear in Fallout 2 and Fallout 4, and are mentioned in Fallout: New Vegas.
