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 worms get inside a person's body when a mosquito carrying their larvae sinks its proboscis into a victim's skin. The larvae travel through the skin and into the lymph vessels where they mature into adults measuring as long as four inches (100 millimeters).
