Do spiders overwinter as adults? Most of the crawling creatures that I tend to spot this early in the spring are quite small, so it was a little surprising to spot several large Wolf Spiders ( probably Tigrosa georgicola) on Monday at Prince William Forest Park. I was pretty sure these spiders had not hatched recently, so I did a little research and learned that “a surprisingly large number of spider species overwinter as adults or immatures, forsaking the cozy shelter of an egg sac in which to endure the harsh, cold extremes,” according to a blog posting by Bug Eric entitled Spider Sunday: Spring Spiders.
The spider in the first photo was actively crawling about in the leaf litter when I first spotted it, probably searching for prey, given that wolf spiders do not spin webs and instead are opportunistic hunters. The second spider was scurrying down a trail at a surprisingly fast pace when it paused for a moment to let me capture an image.
I encourage you to click on the photos to get a closer look at the fascinating details of these spiders, including their multiple eyes and the spiky hairs on their legs.
