Is this a brown recluse spider? #194952
Asked June 27, 2014, 7:05 PM EDT
This isn't exactly a garden question, but it is about insects. I live in Eagan, and there was a spider about the size of a quarter in my basement last night. I managed to get a picture of it. I posted the picture on Facebook and asked if anybody knew what kind of spider it was, and they all said it was a brown recluse. Now, I know brown recluse spiders aren't indigenous to Minnesota, but I did read about the one reported incident. Unfortunately, the picture isn't high enough quality to see if there is a dark fiddle pattern on it's back. I had seen it once before when I picked up a shirt that was on the floor, that hadn't been moved in a few weeks. It immediately ran very fast and I had gone to step on it. When I lifted my foot it looked like it was dead, but it all of a sudden got up and ran under the couch. That was about a week ago. When I saw it last night, it was on the wall of the basement after I had turned the light on. Remembering how fast it was, I decided not to try and squish it. Instead, I vacuumed it up. My question is, do you think it was in fact, a brown recluse, or was it something else? If so, what type of spider matches that description? Thank you for your time.

I can't tell from the image what kind of spider it is because the clarity is just not there. But isn't so interesting that an arachnologist (me) can't be sure if this is a recluse or not, yet all those other people who viewed it on Facebook are sure that it is a brown recluse? This happens all the time and causes unwarranted panic and arachnophobia. Most people know 4 spiders. If it is big and hairy it is a tarantula, if it is black and shiny, it is a black widow. If it is brown, it can't be anything else but a brown recluse despite the fact that there are probably 3,000 species of brown spiders in North America. (And the last one they know is something special like a jumping spider or orb weaver.) You are correct that you are out of the range of the brown recluse so considering that only 2 or 3 brown recluses have EVER been found in your state, what are the chances that you found one? I would say you should rest assured that it was not a brown recluse. If you ever get another one, try to capture it and take a better picture and resubmit.
