Biology
Collingwood (1979) - This ant has been recorded sometimes in large numbers and sometimes as one or two individuals in nests of various Myrmica host species including Myrmica rugulosa, Myrmica scabrinodis and Myrmica sabuleti. A colony in Dorset, England, was observed for over 4 years during which time alate queens and males of the parasite were present each season together with workers and worker brood of the host, indicating that egg laying queens of both parasite and Myrmica host were surviving together in the same nest. In Norway 2 dealate queens were caught in pitfall traps in July 1974 suggesting that after mating, fertilised queens wander over the ground in search of a colony of the host species.
