Milesia is a genus of very large hoverflies,[10] which mimic social wasps.

For example, the European species Milesia crabroniformis is a convincing mimic of the hornet species Vespa crabro.

Milesia are predominantly Palaeotropical in distribution almost entirely Oriental.

[11] The Larvae are of the short-tailed type, found in decaying heartwood of deciduous trees, including rot-holes.
