Bloodbug (Fallout 4)

Bloodbugs are a species of mutated, ectoparasitic mosquitoes found in the Commonwealth in 2287.

Biology
The bloodbug appears to be a monsterously enlarged form of mosquito. Likely a byproduct of mutation caused by nuclear fallout, they have grown in size over the time period since the bombs fell in a similar manner as radroaches and bloatflies.

Bloodbug larvae appear to be roughly two feet in length from the head to the tip of the abdomen. Bloodbugs possess muddy brown coloration which allows them to camouflage effectively into the environment of the Commonwealth. Like their pre-War ancestors, Bloodbugs possess six long double-jointed limbs, two pairs of finely-veined wings, and a long, pointed proboscis that extends from between two compound eyes. This proboscis is the bloodbug's primary means of assault, sinking the proboscis into its prey not unlike a syringe, inflicting minor-to-intermediate radiation poisoning on the victim. This proboscis can be collected by the Sole Survivor upon the bloodug's death.

Gameplay attributes
Bloodbugs latch onto their prey in an attempt to drink their blood. The insect then becomes engorged with the victim's blood, and can spit the contaminated blood back at its target for a large amount of radiation damage, which suggests that radiation is transmitted from the mutant to the victim. The mutated mosquitoes can also spit acid at far away targets.

Bloodbugs are often encountered feeding on Brahmin, a good way to know there are Bloodbugs in the area is to note the corpse of the Brahmin; if it is a skinny, grey husk - then Bloodbugs are nearby.

Bloodbug
The most common variant of the bloodbug. Found in numerous locations throughout the Commonwealth, with encounters possible mere minutes after the Sole Survivor has left Vault 111.

Red widow bloodbug
A rare variant of the bloodbug that is found in the Glowing Sea, and in some other areas randomly in the Commonwealth but generally rather far from Vault 111. Of similar size to normal bloodbugs, but its body is tinted red, it is more aggressive and deadlier then other variants.

Glowing bloodbug
A rare variant of the bloodbug that has a green colorization and has been irradiated.

Bloodbug hatchling
A younger, weaker variant of the adult bloodbug. Common in the area around Sanctuary Hills, the road between Concord and the Red Rocket truck stop early in-game, making it likely to be one of the first enemies the Sole Survivor comes across in their travels.

Infected bloodbug
One can be found in the basement of the Greater Mass blood clinic. It is initially non-aggressive, and even killing the surrounding Bloodbugs does not incite it to attack. This variation can also be found a lot in the Glowing Sea, where it is hostile like all other bloodbugs.

They possess more health than a normal adult bloodbug, and deal more damage per hit. Some have a green skin to them, but it does not glow.

Vampiric Bloodbug
The Vampiric Bloodbug can be found in locations throughout the Commonwealth.

Legendary vampiric Bloodbug
The Vampiric Bloodbug can be found in locations throughout the Commonwealth.

 * If entering the Pip-Boy right before the blood-sucking animation, the Sole Survivor will pull up their hands as if holding a gun. One will not see the Pip-Boy but it will still function. The only known fix is to reload a previous save.
