Myrmica hirsuta

This species is a social parasite found in the nests of Myrmica sabuleti.

Identification
Similar to a microgyne Myrmica sabuleti but distinguished by the laterally enlarged post petiole, wider frons and excessive development of body hairs. Head width: 1.05 mm. Body length: 5.2 mm. Mean postpetiole width: 0.675 mm. (Collingwood 1979)

Distribution based on Regional Taxon Lists
Palaearctic Region: Austria, Croatia, Czech Republic, Denmark, Finland, Germany, Hungary, Netherlands, Poland, Russian Federation, Serbia, Slovakia, Sweden, United Kingdom of Great Britain and Northern Ireland.

Fennoscandia, Denmark and the British Isles
Collingwood (1979) - This species was discovered by Elmes (1978) in a small group of colonies containing apparently normal Myrmica sabuleti workers and in some cases normal queens. The small queens were at first assumed to be microgynes of M. sabuleti but body pilosity and relative postpetiole measurements were found to be outside the range of that species. In size and appearance M. hirsuta resembles Myrmica myrmicoxena Forel found once only as a parasite of Myrmica lobicornis in Switzerland and also has affinities with the similar but much larger Myrmica bibikoffi Kutter (1963).

Castes
Queens and males are commonly present. Workers are relatively rare in this social parasite.
