Bloodbug (Fallout 4)

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

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

Biology
The bloodbug appears to be a greatly 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.

Hatchlings appear to be roughly two feet in length from the head to the tip of the abdomen. They possess muddy brown coloration which results in an ability to blend quite effectively in many of the environs of the Commonwealth. Like their pre-War ancestors, they also 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--the bloodbug sinking it into its prey not unlike a syringe in order to suck blood--and in the process inflicting minor-to-intermediate radiation poisoning on the victim, as mentioned below. This proboscis can be collected by the Sole Survivor upon death of the bloodbug.

Gameplay attributes
This creature latches onto the Sole Survivor and NPCs in an attempt to drink their blood. It then becomes engorged with the victim's blood, and can later spit the blood back at the target for a large amount of radiation damage, suggesting that radiation is transmitted from the mutant to its victim. It can also spit acid at far away targets.

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.

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
A seemingly rare variant, one being comfirmed 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. They seem to possess more health than a normal adult bloodbug, and deal more damage per hit. They have a green skin to them, but it does not glow.

Appearances
Bloodbugs appear in Fallout 4.

Behind the scenes
The bloodbug model was created by Jonah Lobe.
