If a bat that weighs 7 g eats half its body mass in insects every night (typical), I think that works out to 1400 mosquitoes needed based on a 2.5 mg mosquito. So more than 2 mosquitoes every minute if hunting for 10 hours. [Please check my math.] Doable, perhaps, in a room packed with thousands of mosquitoes but in the real world that bat would starve to death. Because it takes more energy to find and hunt down a tiny fly than it gets from the fly. Small bats DO eat mosquitoes but never enough to be important in control. My 2 cents.

And as far as I know, nobody has ever photographed a bat catching a mosquito in the wild.

@colinpurrington@flipping.rocks Now do flycatchers.

@colinpurrington@flipping.rocks I imagine, like possoms, that they're happy to eat mosquitos in the course of their lives but don't focus on them. OTOH, if articles like that make more people happy to see bats in their neighborhoods, it's a win all around.

@colinpurrington@flipping.rocks I’m not gonna check your math because it sounds solid, but if not bats, then what IS eating mosquitoes?
