How do bot flies lay eggs?

Eggs: Female Dermatobia hominis adults deposit their mature eggs on a blood-feeding arthropod, usually a mosquito or a tick, that is captured by the bot fly in flight. This behavior is known as phoresy (Safdar et al. 2003). As the vector takes a blood meal, the bot fly eggs react to the change in temperature and hatch.

What are botflies and how do they spread?

The botfly is a parasitic fly that has its larvae grow inside a host, including humans. The female botfly starts by grabbing a mosquito in mid-air and attaching several of its own eggs onto it with a sticky glue-like substance. When they can’t find any mosquitos buzzing around, they sometimes resort to sticking their eggs onto ticks and vegetation.
