The species is found in North America, from Canada to Mexico, nesting deep within the ground. Unusual among ants, Prenolepis imparis prefers lower temperatures, including near freezing, and is only active outside the nest during winter and early spring. [2] Prenolepis imparis enters a hibernation-like state called aestivation during the summer.
Another common winter migrant insect, found in much of North America, South America, and the Caribbean, is the green darner. Migration patterns in this dragonfly species are much less studied than those of monarchs. Green darners leave their northern ranges in September and migrate south.
Carpenter ants (Camponotus spp.) are large ants (workers 7 to 13 mm or 1 ⁄ 4 to 1 ⁄ 2 in) indigenous to many forested parts of the world. [ 4 ] They build nests inside wood, consisting of galleries chewed out with their mandibles or jaws, preferably in dead, damp wood.
These ants are commonly called "crazy ants" because instead of following straight lines, they dash around erratically. They have a broad distribution, including much of the tropics and subtropics , and are also found in buildings in more temperate regions, making them one of the most widespread ant species in the world.
Black carpenter ants are polymorphic, workers can be in different sizes. The queens can reach a length of 19–21 mm and the largest workers (super majors) can achieve similar sizes of around 14–17 mm . They, along with several other Camponotus species, are among the largest species of ant in North America. As with all ants, the antennae are ...
Colonies of real army ants always have only one queen, while some other ant species can have several queens. The queen is dichthadiigyne (a blind ant with large gaster) but may sometimes possess vestigial eyes. [5] The queens of army ants are unique in that they do not have wings, have an enlarged gaster size and an extended cylindrical abdomen ...
Scientists have some good news for rats and some bad news for city dwellers. Rat populations are rising in cities including Washington, D.C., and San Francisco, reports a study released Friday ...
While the battles of other ant species generally constitute colony raids lasting a few hours, or skirmishes that occur periodically for a few weeks, Argentine ants clash ceaselessly; the borders of their territory are a site of constant violence and battles can be fought on top of hundreds of dead ants. Fights may be halted by adverse weather ...
