Microdon analis, is a species of hoverfly. It is found in the Palearctic. The distinctive almost slug-like larvae live in ants nests. The larvae are hemispherical in shape and heavily armoured. They are believed to prey on the eggs and larvae of a number of different ant species, notably Lasius niger and the Formica rufa group. These ants are usually found on heathland.[1] However Schmid (2004) claims that Microdon analis and M. major which are cryptic species have been confused under the name analis . M.major is apparently associated with ants of the genus Formica, the other species , M.analis, with Lasius species.[2]
