It is also found in parts of California and Washington. The pedicel, which connects the thorax and abdomen, has two segments. The swarmers or reproductive ants are winged, about twice the size of the workers, and also have a furrowed head and thorax. The spines are evident on the females but absent on the males. Very little information is available on pavement ant colony biology.
Most information is gleaned from the observations of ant behavior aboveground.
Winged reproductive ants typically swarm in the spring but have been known to emerge any time of the year in heated structures. It is not uncommon to see swarming in late fall and into February even in colder climates. After emergence, the ants mate and the queens burrow into the soil to begin laying eggs. Most colonies are located under sidewalks, building slabs, and large rocks. Ants enter buildings through cracks in foundation walls and interior slabs.
