I found this beauty earlier today as I was pulling out some supplies for my class. It's a wolf spider (i'm pretty sure it is...) but I couldn't be specific about what species of wolf spider (there are about 125 different wolf spider species in North America alone.)
The wolf spider does not build a web to trap its prey. Instead it hunts at night - rather like a wolf. They tend to be solitary spiders -unlike wolves- often found, as this one was, near doors and windows.
Their bite, while painful, is not likely to be fatal.
