Urban species #243: Pavement ant Tetramorium caespitum

Little piles of dirt form on sidewalk cracks, busy with tiny goings-on. Only an eighth of an inch long (3mm), each pavement ant is a member of a colony of perhaps three of four thousand individuals. There are several queens in each colony, a fact that probably contributes to the great success and wide distribution of this species. This ant is native to Europe, but like many other European invertebrates (including, but not limited to the nightcrawler, woodlouse, woodlouse spider, pill bug, and ground beetle) was introduced elsewhere in the soil ballast of ships. The cities on eastern half of North America can claim this ant as one of their most familiar creatures, and it is found in some Pacific coast places as well. Pavement ants collect carrion and insect carcasses, and will feed on a variety of different trash items also.
