The largest british ant species, creating prominent nest mounds mainly in woods throughout Essex and southern England
They feed mainly on insects found near to the nest, and especially on aphids and the honeydew that they produce
Often introduced into commercial woodlands as a means of pest management
Recognition

Young queens and males are winged and have a heavier thorax; the wings are shed after mating
The workers are voracious hunters, driving prominent trails through their teritories
Lifecycle
Nests are usually built along woodland rides or in woodland clearings, and sometimes on open heaths
Huge numbers of winged males and females leave the nest on a warm day in June to mate
The male dies after mating, while the queen searches for a good place to start a new nest
