The female botfly glues her eggs onto the abdomen of a captured mosquito or other common fly. When the carrier insect lands on a human, the larva, or bot, hatches, burrows into the skin, and positions itself head down to feed, breathing through caudal respiratory spiracles.
The mature maggots, which may be an inch long, then drop out of the rodent or rabbit host and pupate in the soil. Cats become infected with a botfly larva when they come into contact with a blade of grass that has a maggot on it. The movement of the cat against the blade of grass stimulates the maggot to crawl onto the cat. The maggot then crawls around on the cat until it finds an orifice in which to enter.
