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]
