It often looks like insects have totally disappeared from the winter landscape. Well, in most cases they actually haven't gone anywhere. Despite the fact that insects are cold-blooded and rely on the temperature of their surroundings to keep them warm, insects have been successful in developing methods for surviving during the cold, winter months.
Many insects pass the winter in the egg stage.
Insect eggs are ideally suited for withstanding the hardships of winter. The eggs have shells that are thick and water-tight. In many cases the eggs are covered with hairs, silk, or frothy materials produced by the female before she died. These provide an extra degree of protection by insulating the eggs. Other insects enter into a special type of hibernation known as diapause.
