Migration is one strategy for escaping the killing temperatures. The Monarch Butterfly is the foremost example of this maneuver, but other insects migrate into northern areas from the southern states in the Spring. Crop pests are the most obvious of these migrants. Overwintering as Larvae. Many insects successfully pass the winter as immature larvae.
Some grubs simply burrow deeper into the soil to escape the cold.
Overwintering as Nymphs. Not many insects are active in the winter, but the nymphs of dragonflies, mayflies and stoneflies live in waters of ponds and streams, often beneath ice. They feed actively and grow all winter to emerge as adults in early spring. Overwintering as Eggs. Lesser numbers of insects lay eggs which survive the winter.
