That means that 9 out of every 10 animals is an insect. They all have an exoskeleton divided into three sections, three pairs of legs and a pair of antennae. We often think that insects disappear during the winter. It's true that a few insects migrate to warmer regions to beat the cold. However, most are still with us, we just don't know it.
Many insects survive the winter in the egg stage.
Insect eggs often have thick, watertight shells insulating the precious cargo inside. Others enter a type of hibernation known as diapause. The insects go into a deep rest, reducing their energy needs. Insect diapause is affected by the amount of daylight, rather than temperature. This way, insects are not tricked into coming out hibernation too soon because of an unusually warm, winter day.
