Mosquito

In a U.S. National Park, an alien spacecraft crashes down, causing mosquitos to mutate into giant size after feeding on its corpse. As lovers Megan (Rachel Loiselle) and Ray accidentally hit one of these monstrous insects with their car, they join forces with park ranger Hendricks (Ron Asheton), bank robbers Earl (Gunnar Hansen) and Junior, and meteorologist Parks (Steve Dixon) to fight for survival against the deadly swarm.
