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.

Giant Wood Hoverfly

A large, wasp-mimicking hoverfly with yellow and black banding and a slender waist. Its larvae develop in decaying wood of fallen trees in old-growth forests.

💡

Did You Know?

It is considered an indicator species for ancient woodland due to its dependence on large volumes of decaying timber.
