Fallout: Baton Rouge
Louisiana mosquitoes were nothing to shake a stick at before the world went to hell. After genetic manipulation and the bombs they are now a genuine horror. Averaging to about the size of a sea gull with a nearly foot long proboscis. Alone they are annoying but they tend to swarm in large groups which are known to be able to drain a small family dry in minutes. The largest swarms can be identified from a distance by the stringy web of bloody mucus linking the swarm together in gruesome decoration.
