Habitat & Breeding
A wide range of locations, ant colonies can sometimes be in close proximity to human dwellings, entering buildings to forage for food. Sometimes nests can be found well inside factories with the ants exploiting proofing defects such as cracks in the building fabric. The queen ant lays a variable number of eggs. Three to four weeks later legless grubs hatch, three weeks later larvae mature, two weeks after pupation adult ants emerge. Late summer winged and mature males leave nest and mate and the males die whilst the females find new nest sites. Many thousands of ants live in a nest in a social hierarchy tending to various functions.
