![]() Their daily activities continuously move them toward warmer climates, and the insects never really experience prolonged cold weather. Other insects, such as dragonflies, engage in a less direct migration. These insects usually engage in a one-way migration to warmer climates to the south where they reproduce, die and send a new generation northward to begin the cycle again. Some insects, Monarch Butterflies are a prime example, outrun the cold weather by migrating away from it. Their eggs, however, overwinter and will hatch in the spring, bringing forth a new generation of these pests. Adults (and immature nymphs) can't survive cold, winter temperatures. They do so by laying eggs in sheltered areas or providing their larvae with food and shelter to survive the winter, often at the expense of their own well-being. These insects often spend their last days preparing the next generation for the upcoming spring. Most of these have already completed their true mission in life – to reproduce.

These are the kinds of questions you may be wondering when you’re wiping ants off your kitchen countertop or spraying wasps that have accumulated in your window screen.įor many insects, the change in temperature is a matter of life and death. Where do bugs go in the winter? How do they make it through to spring? Doesn’t anything kill these things?
