During the fall, it may feel like all the spiders in the area have found their way into your home and plan to spend the winter with you. But aside from those home invaders, there are millions more spiders that pass the winter outside. How do they survive? Animals have developed special adaptations to help their species survive long, cold winters, and spiders have some unique and interesting ways of doing it.
First, it is important to note that spiders are cold-blooded creatures. This means that their body temperature changes with their environment. When it is cold outside, spiders simply become less active to conserve energy. Since their metabolism is related to the temperature, they do not need as much food during cold weather. Many spiders enter a dormant stage called diapause, which is similar to hibernation.
Spiders also have the unique ability to create antifreeze-like compounds in their hemolymph (blood). The glycol and protein starts accumulating as soon as the temperatures start to get colder, which lowers the freezing point of a spider’s blood and allows them to survive much colder temperatures. Similarly, some species of spiders will intentionally dehydrate their bodies so that freezing will not harm them. When the winter is over, they can rehydrate and continue on as normal.
Some spider species mate and lay eggs in the fall, after which the adult spiders will die. Since spider eggs often have a difficult time surviving freezing temperatures, in many species the eggs will hatch, and the baby spiderlings will stay in their egg sac throughout the winter. When the temperatures warm up again, they will chew their way out of the sac.
Those species of spiders that hatch during the spring and summer months will overwinter as adults. Finding shelter is very important and must be carefully chosen. Places where spiders like to shelter include: chimneys, downspouts, burrows, wood piles, leaf litter, cracks and crevices, under loose bark, rock piles, and inside homes.
