Do bats eat mosquitoes? I'd imagine mosquitoes are too small for the energy bats spend flying to catch them to be worth it.
This particular species feeds on Lepidoptera mainly, but Diptera are the second group most preyed upon (45% of diet, including mosquitoes). Smaller bats eat more mosquitoes, but is not clear how much. Each bat should eat between 600-1000 a night to survive only on mosquitoes. Fat juicy moths are preferred when available.
