Bloatfly (Fallout 3)

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

Background
The resulting radioactive fallout after the Great War mutated the tiny blowfly into the larger bloatfly menace that is potentially lethal even at medium to long range.

Biology
Bloatflies attack at long range by shooting their prey with spine-bedecked larva launched from its abdomen. This supply of larva is seemingly inexhaustible, and unless evaded or eliminated, bloatflies will persecute an attacker relentlessly. They are covered in a green-brown carapace. Bloatflies typically live in small groups of two to four individuals, but can be encountered on their own.

Game attributes
Individually, they do not inflict much damage, but in swarms, bloatflies can be a moderate threat to low level players and deadly to weak companions.

Their carapaces are not particularly effective when trying to protect against any type of weapon, thus they are easy to kill, assuming you can hit them. Due to their erratic movements, bloatflies can be challenging to hit at times.

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 of some dead wastelanders and between Fort Independence and Fairfax Ruins, on the hillside near a collapsed overpass highway.

Appearances
Bloatflies appear in Fallout 3.
