The remaining species are mostly . These include the well known wood ants, typified by the southerly inclined "Formica rufa", and the more northerly "F. lugubris" and "F. aquilonia". These large, noticeable species abide in mounds constructed from leaf litter, which are still a common sight in many older forests and broken woodland up and down the country. A few other smaller, less easily spotted species also make their livings in conjunction with more wooded areas. "Stenamma" species, "Leptothorax acervorum and Temnothorax nylanderi" can be found, locality permitting, under stones/logs and beneath loose bark respectively, in established woods. The former habitat is also shared by the rather locally distributed "Ponera coarctata", one of two unambiguously native British representatives of the subfamily Ponerinae. The other is the recently discovered "P. testacea", which inhabits sites.
