The bumblebee is the most frost-resistant insect. He knows how to contract the pectoral muscles, accelerate the blood, thereby warming the body up to 40 degrees. Thus, he feels great even in an unheated atmosphere.
The number of one family can range from 100 to 500 individuals.
For example, in bees, this number is much higher. They live almost everywhere. The exceptions are Australia and Antarctica.
Huge queens can reach 3 cm. The nests are located on the ground.
