Many insects survive the frigid cold temperatures, such as Michigan, by hibernating or migrating. The monarch butterfly travels all the way to central Mexico to hibernate in masses on trees. Monarchs that were living west of the Rockies travel to Santa Barbara, California for their hibernation. Many moths take off to warmer areas as well.

Most insects hibernate, but not all in the same life cycle stage. Some bugs, like bees, termites, lady beetles, group together among their own kind in protected areas for warmth to wait out the freezing temps. Ants do eat to put on some fat, then often head below the frost line and huddle around the queen as they live off their stored fat and carbs.

Many insects go into a long-term state of suspension (diapause) that synchronizes with different stages of life cycles. Within the first cycle, praying mantises, crickets, some mosquitoes remain dormant as eggs within the soil until spring. Spending the winter in the second stage, or larvae, are wooly bear caterpillars. They curl up in thick layers of leaves. Some flies and mosquitoes are dormant in this stage as well. The third stage as a pupa, are resting flies, the black swallowtails within their chrysalises emerge as butterflies in the spring. Numerous moths develop during this time within their cocoons. Mourning Cloak butterflies hibernate as adults, tucking into loose bark or tree cavities. This adult stage is true for some mosquitoes. Having mated in the fall, the male dies. The female finds a hidden protected area until spring and searches for that first bloodmeal so her eggs can develop.

Another adaptation for some insects is the development of their own antifreeze. In the fall their bodies produce higher levels of glycerol, giving them a super cooling ability. Tissues and cells aren’t damaged when bodily fluids drop below freezing. Those glycerol levels drop as spring arrives.

Now there are a number of pests that find another place for winter, your home. Cockroaches, scorpions, spiders slip into wall voids and attics. Those left in the wilderness seek refuge in hollow logs or cavities in nature. The silverfish is a whole other story. They stay active all year long and live for three years. Loving high humidity, munching on paper and synthetic fibers. Catching them early is crucial.

Spring, such a lovely time to see renewed life and enjoy the outdoors. But not all forms of life make our lives enjoyable. Get ready. They’re coming soon.
