The bites leave animals anemic and bleeding under their skins, and they also become exhausted from constantly moving in an attempt to avoid the insects.
It happened in the One Punch Man anime. There is a movie called Mosquito, but they are giant sized instead of a swarm. Land of the Lost had a giant one that mostly drained what’s his name.
For movies they appear to have consistently gone with the giant mosquito approach.
Special mention: The spiders in Arachnophobia drained people completely despite being about wolf spider sized, which is smaller than a tarantula.

You’re telling me that tarantulas can be bigger than a wolf?
Bigger than a wolf sized spider?
No.
They also did it in Solar Opposites.
