The hibernation of ants.

As winter approaches, one wonders how the ants adapt to the cold.

Ants are so-called "cold-blooded" insects, that is to say that their body temperature varies with ambient temperature, unlike mammals or birds which have a stable body temperature.

Thus, when it is cold, the ants' body temperature is low, and the disadvantage is that at low temperatures they are inactive and their muscles cannot function.

In winter, Ants stay sheltered in their anthill, sinking to a certain depth in the ground, in rock cracks or in worm-eaten wood, where the temperature does not generally drop below 0 ° C , because frost can be a formidable enemy.

Ants are not completely defenseless against frost: as winter approaches, they produce antifreeze substances that protect them, allowing them to resist light frosts.
