How Bats Hunt
Flying around all night is pretty exhausting for bats and many of them roost for periods of time to conserve energy. Perch and wait is a strategy to sit, or rather hang upside down, until an insect flies by. Bats also use their incredible hearing to locate insects that are walking around on crop or tree leaves and then swoop down and pluck them off the actual plants. This ability means that caterpillars and other larval forms of insects that don’t fly or even adults that seldom fly are a large part of bat diets, even ants on the ground are eaten as bats are incredibly maneuverable in flight. Bats value in pesticide use reduction is easier to measure in agricultural crops but Susan Loeb, US Forestry Agent stationed at Clemson, said they are equally important in eating harmful insects in our woodlands.
