Southern Wood Ant Formica rufa
....
Nottinghamshire's largest Ant and restricted to just one area of private woodland in the east of the county. Formica rufa makes large dome shaped nests of pine needles and small twigs. This creates a weather-proof thatch, which in turn creates warmth within the nest. The nest temperature is regulated by the workers throughout the course of the day, with entrances sealed at night to maintain heat. Workers are very defensive and can spray formic acid in defence, but this is actually not as bad as it sounds. Photographed in late March 2009.
