Ant family

There is only one mother (queen) ant

Although there are many winged female ants in one nest, there is only one mated female, the mother, whose wings fall off. This means that ants in the same nest are all brothers and sisters.

The male appears only once a year and waits in the nest for the day of mating. After the mating, the male dies without returning to the nest. The male is not usually seen in the nest.

Ants are white at birth

Sometimes, workers of Formica japonica become naked pupae by biting through their cocoon before they develop color. As a result, they look white at birth because the body is uncolored. These white-colored ants also assist with work in the nest.
