Formica lemani

Worker on a lichen covered rock. In marginal upland areas such as mid-Wales this species can survive by nesting in small areas of exposed, south-facing rock, even in habitat that seems otherwise unsuitable.

Camponotus piceus

A queen about to take her nuptial flight. Taken in the French Pyrenees, this species is common and often abundant through Southern Europe.

Formica sanguinea

Two workers of this slave-making ant almost co-operating. Stedham Common, Sussex.
