Bot Fly
Parasitic fly whose larvae develop under the skin of mammals including humans. Female captures a mosquito and glues eggs to it — when the mosquito bites, body heat triggers egg hatching.
Did You Know?
The human bot fly is so devious it hijacks mosquitoes — it catches them, glues eggs to their bodies, then the eggs hatch when the mosquito lands on warm skin.
Twin-lobed Deer Fly
A golden-green eyed deer fly with distinctive dark wing markings. It breeds in peaty wetlands and bogs across northern regions.
Did You Know?
It is one of the most common biting flies encountered in northern European bogs.
