How Do Ants Survive Winter?
WouterDuring the coldest months of the year, some species of ants survive by hiding in the cold. In other cases, they find ways to stay warm. For instance, some species of ants will form colonies underneath large rocks or stones. These structures serve as solar collectors, keeping the ants warm.
Some ants build huge mounds of dirt, which absorb radiant heat from the sun and warm the colony below. Some ants form smaller colonies, which are connected by a loosely knit network. This way, the colony can survive the winter and thrive in the spring.
Some ants convert fat into a substance that prevents ice crystals from forming in the ants’ bodies. This is called diapause. During diapause, ants do not eat, drink, or lay eggs. Their metabolism slows down dramatically. This process allows ants to conserve energy for winter activities.
A common tactic ants use to stay warm during winter is to build a large mound of dirt, which absorbs the radiant heat of the sun. The mound can also serve as a shelter for the colony. During the winter, ants will seek out warm places and avoid crossing paths.
Another way ants keep warm is by using a substance called glycerol. This compound is found in antifreeze. Glycerol is a natural antifreeze and ants have the ability to convert this substance into a form of energy. Glycerol can prevent the formation of ice crystals in the ants’ bodies and helps them to regulate their internal temperature.
