Bloatfly (Fallout 3)

Bloatflies are mutated insects living in the Capital Wasteland in 2277.

Game attributes
Individually, they do not inflict much damage, but in swarms, bloatflies can be a moderate threat to low-level player characters (especially companions). Their carapaces are not particularly effective as a protection against any type of weapon. However, due to their fast, erratic movement and small size, compared to other denizens of the wastes, bloatflies are a challenge to shoot without V.A.T.S.. They have a slow speed of pursuit, making it easy to escape them even with low Agility.

Bloatfly
Bloatflies are enormous blowflies. In significant numbers they pose a minor threat to high-level player characters, but can prove lethal to low-level characters.

Locations
A large group of bloatflies can be found throughout the entrance area of Vault 92. Two other significant locations are northeast of Reclining Groves Resort Homes, where they feed off the corpses of some dead wastelanders, and between Fort Independence and Fairfax ruins, on the hillside near a collapsed overpass highway.

Sounds
