Small ants with pale brown to black appearance.
The name comes from the fact that it used to do their nests under the pavement of our sidewalks or in the cracks of the asphalt. The nests are easy to spot because of the small mound of sand that can be observed at their entrances. These ants are all of the same length and can reach several thousand individuals per colony. Sometimes they make their nests in empty structures or even below the concrete slab, making it difficult to control.
Omnivore, pavement ants eat many different foods, but they prefer fatty and sugary foods.
A colony can contain from 1,000 to 4,000 individuals. A colony can host multiple queens. The winged reproductive male and female, come out normally in June or July (swarming period), but they can occur anytime.
Of dark brown to black gray color, male ants and workers do not exceed 3 to 5 mm, but the queen reaches 8 to 9 mm of length.
The black ants inhabit all environments, mainly damp places. They are found in the plains or mountains, in meadows, along the paths, in the forest, gardens and they occasionally slip into the houses.
Black ants feed primarily on sweet secretions emitted by aphids and scale insects, the honeydew.
Their nest, covered by a dense network of galleries, is installed in loose soil, under stones, in decaying tree stumps and under bark. It houses one queen. In midsummer, the young insects leave for mating flights often gathering in large numbers. Shortly after mating, the males die and the fertilized females, who each lose their wings, found a new colony by laying eggs in a small cavity.
Larvae not pigmented and recalling the maggots are provided with food by workers, they pupate in white cocoons.
