Pisaurina mira
(Nursery Web Spider)

Actually, I am pretty sure it’s a yellow sac spider. I did more research than I would have liked yesterday, considering that spiders give me the hibby gibbies. They are poisonous, but not life threatening. We have seen two here, and have kids. We’re going to take action to repel them as best as possible. Thank you both for your help.

I believe that the lighting here is affecting a correct identification. I seen this baby in real life. I compared it to images on the Michigan State University’s website, in the section about spiders in Michgan. The spider in my window looked nothing like a nursery web, and exactly like a yellow sac spider. Sorry to be so forward, but I’m sure that I’m correct, and I don’t want this thing mis-identified, seeing since it is poisonous and can make people sick.
