This large spider has taken up residency in our back room window, which is generally never opened.
My husband and I need someone to settle the bet! Is s/he a Brown Recluse?
I think it has many of the characteristics of one, but my hubby doesn’t agree.
This spider has grown, and has shed its skin, too…
Thanks 
Please email your answer to Robin or leave it in a comment. Thanks!
It doesn’t look like a brown recluse. It also wouldn’t tolerate you near it’s web. I got bit in the summer of 2011 and ended up with complete heart and organ failure. Was in the hospital for three weeks. I had one in my house about a month ago – Scared the hell out of me.
It looks similar to a common spider here in Florida called the green lynx spider. We see them in the fall on wildflowers catching butterflies and other insects.
Does it build a big web? I would guess a Araneus species, and probably a common barn spider A.cavaticus. You can safely stay in your house.
