Bloatfly (Fallout: New Vegas)

Bloatflies are mutated insects living in the Mojave Wasteland, Zion Canyon, and Big MT in 2281.

Biology
A bloatfly is a mutated blowfly with a green-brown carapace. Unlike the Capital Wasteland variety, bloatflies in the Mojave are largely docile, rather territorial and far less common. They are usually found around graveyards or pools of radiated water in groups of three to five.

Gameplay attributes
Weak by nature, their attacks have very little effect. Their main attack consists of spitting spiked larvae at the player from a distance. They are relatively easy to kill in close combat, even if the player lacks any substantial skill in Unarmed or Melee Weapons, as they have very little health. However, it can be a bit tricky to hit them with a ranged weapon without the assistance of V.A.T.S., as they tend to move rapidly in sporadic patterns.

Unlike most other inhabitants of the Mojave Wasteland, bloatflies will often leave you alone if you walk away.

The normal variant with all of the attributes noted above.

Legendary bloatfly
The legendary variant found in the Big Empty in the location marked Mysterious Cave. It is quite bigger than the average bloatfly and has a pale green glow around it, making it easier to spot in the cave. Unlike normal bloatflies, it fires an extremely high damage plasma like projectile from its tail and will explode like a plasma grenade when killed. Like Gabe, the legendary bloatfly's immense size is suggested to be caused by a massive intake of chems. Notably, Buffout and psycho.

Locations

 * Their natural habitat is generally the various tar pits, puddles, and graveyards throughout the Mojave Wasteland.
 * A large number of bloatflies can be found west of Powder Ganger Camp West.
 * You can also find two to four of them in the beginning of the game in the Goodsprings Cemetery. However, these bloatflies will not respawn.
 * The player is likely to encounter many of them on the way to Primm from Goodsprings, as there are many tar pits scattered along the left side of the road.
 * They may spawn within the Camp Forlorn Hope graveyard next to the camp proper, but will be gunned down quickly. However, they can cause problems if attempting to talk to people outside who are near them, like Private Stone, as if the player is threatened the people in the camp will run around panicking. This can be amusing, though they cannot be talked to, thus preventing progressing with some quests. This can be solved by killing the bloatflies.
 * Several bloatflies can be found behind the Jean Sky Diving shack, usually fighting with some Powder Gangers.
 * Some can be found around the Wrecked Highwayman.
 * They infest the Mysterious cave in Old World Blues.
