Habitat: Larvae develop inside a host animal.

Foods: Larvae eat body fluids or tissues of their hosts (hares, squirrels, caribou, marmots, and other mammals). Foods of the adults are unknown.

Eaten by: Insect-eating birds

Do You Know? Bot flies lay their eggs on their host's skin. The larvae burrow under the skin and feed on tissues or body fluids of the host, then emerge and drop to the ground where they develop into adults who will continue the cycle.
