Tachina fera is a species of fly in the genus Tachina of the family Tachinidae. It was first described by Carl Linnaeus in 1761.

It is also present in Israel and North Asia, east to China, Mongolia, Korea, and Japan, and in North Africa.
These flies inhabit the vegetation of humid regions, meadows, woodland, forests, forest edges, clearings, heath and moorland and natural gardens. Tachina fera can reach a length of 9–14 millimetres (0.35–0.55 in), with a wingspan of 16–27 mm.

They are bristly on the thorax and abdomen, especially towards the tip, where they have long thorn-shaped, protruding black bristles.

GBIF citizen-science records
It is estimated from how often the Common Tachinid is recorded against all the insects logged in Rotterdam [The Hague] (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
