Films: Mosquito (1995)
Location: Forest/Haunted home
Height/Weight: That of small dogs.
Summary: The most dangerous animal on Earth is not the great white. Not the grizzly bear. It is the tiny mosquito. The disease-spreading agile flying insect that will go out of its way to bite you and wreck your day. But the good news now is that you can hit them easier. The bad news is that they're violently homicidal this time.
History: A while ago, an alien spacecraft has crash-landed in a national park in Michigan. The occupant is dead, but its corpse is sucked dry by a bunch of local mosquitos. This mutates the bugs into monstrous flying beasts that attack any living creature on sight, sucking up their blood and leaving them as withered, mutilated husks. Bad news for the visiting bank robbers and other assorted folks.
Notable Kills: One robber is sucked so hard that his eyes start bulging out and exploding.
Final Fate: After a whole nest of mosquito eggs is found in the house they're bunked up in, the survivors manage to set the place to explode. It does, taking all the eggs and grown mosquitos with it.
Weakness: Anything conventional, though they are warded off by fire.
Scariness Factor: 4.5-A swarm of mosquitos is bad. An army of gigantic blood-sucking insects is worse. Sure, they don't go down too hard, but they're still more than capable of striking you and giving you a slow painful demise. Also, their models are disturbingly realistic at times.
Trivia: -The mosquitos are directly identified as Aedes aegypti. AKA, the Yellow Fever Mosquito, one of the deadliest breeds. They used to haunt only Africa, but have since spread across the Southern United States. Some of these mosquitos have been genetically modified to render their own kind sterile, though.
-Oddly, the effects team that helped bring the mosquitos to life completely disappeared after going out to smoke cigarettes. They haven't been seen since.
