Скачать или смотреть Tachinid Fly (Tachina fera) - Brighton, October 2020

Tachinid Flies are 'parisitoid' insects which will, as a result of depositing their eggs on or about their hosts, lead to the death of that host, unlike parasites which usually feed off a living host.

There are a number of ways eggs might be deposited. Often they are injected into the host, or lain on the skin of the host where it cannot reach to clean.

Sometimes the parasitoid will target the intended host's favourite food laying eggs, which then either enter the hosts food direct, or which 'hatch and latch', grabbing the host as it passes close by.

Check your next pizza closely.

Tachnida fera is large, common and bristly, generally seen on the wing from May though to early October, in two generations, feeding on nectar.

The fly in the video is probably female as the males usually have dark legs with an orange tip to them, absent here.
