 "Dermatobia" fly eggs have been shown to be vectored by over 40 species of mosquitoes and muscoid flies, as well as one species of tick; the female captures the mosquito and attaches its eggs to its body, then releases it.Either the eggs hatch while the mosquito is feeding and the larvae use the mosquito bite area as the entry point, or the eggs simply drop off the muscoid fly when it lands on the skin.The larvae develop inside the subcutaneous layers, and after about 8 weeks, they drop out to pupate for at least a week, typically in the soil.
