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.
Dogs become infected with a botfly larva when they come into contact with a blade of grass that has a maggot on it. The dog's movement against the blade of grass stimulates the maggot to crawl onto the dog.
