Biology. This is an obligate parasite of Tetramorium caespitum HNS . Queens fertilised within the nest of the host species fly away to secure adoption in other colonies. Queens of the host species are not present in Anergates-Tetramorium nests and only Anergates HNS brood are developed, often in large numbers, from the single adopted Anergates HNS queen whose gaster becomes grossly swollen.
