Bloatfly (Fallout 3)

Bloatflies are creatures living in the Capital Wasteland in 2277.

Biology
The bloatfly is a giant mutated version of the pre-war blowfly. Bloatflies attack at long range peppering 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 harm, but in swarms bloatflies can be a serious 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.

Appearances
The bloatfly appears in Fallout 3.
