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.

Appearances
The bloatfly appears in Fallout 3.
