Classification:
Microdon analis/major belongs to the subfamily Microdontinae, tribe Microdontini.
Distribution:
Palearctic.
Habitat:
Microdon analis: Preferred in deciduous and coniferous forests with overmature trees.
Microdon major: Both open grasslands in humid forests, as well as dry, sub-Mediterranean grasslands and scrubland.
Especially in places where ant nests can be found suited for the development of the Microdon larvae.
Description:
Body length 8 - 11 mm; 3rd antennal segment about twice as long as the 2nd.
Biology:
The larvae of the genus Microdon live in ant nests, where they feed on ant larvae, possibly also on eggs. A Microdon larva eats more than a hundred ant larvae until it pupates. The nocturnal Microdon larvae are on the prowl at night when the diurnal ant larvae are inactive. The larval stage lasts about 11 months. The pupation takes place near an exit of the ant nest.
Hosts of the larvae of Microdon analis and Microdon major are ants of the genera Lasius and Formica.
Annotation:
Microdon analis and Microdon major can only be distinguished by larval or pupal characters.
