I have a real website now rather than a blog. Though I will keep this one open for a while, I will no longer keep this one up. My new site, "USA Spiders" is not fully completed but getting close. I made sure to get the Michigan page finished first. :o) Please use
USA Spiders in the future and if you find any problems with the site, please let me know so I can fix them.

Spiders verified to be here in Michigan are listed on the left sidebar. On the right sidebar, are the spiders of which pictures have been sent in to me.

Wolf Spider

Michigan Spiders - Wolf Spider-3

Michigan Spiders - Wolf Spider-1The Wolf Spider pictured in the above three images was only about the size of a nickle (legs included). Since it is only early May, I would expect to find them a bit larger in the Fall.

Identification – There are several different looking Wolf Spiders, so I mentioned some of the more common patterns seen in Michigan. The best way to identify a Wolf Spider is by the eye pattern. Wolf Spiders have a row of four smaller eyes with a set of two large eyes higher up. Above the larger eyes is yet another set of two medium sized eyes to make it eight eyes in all.

Abdomen – Different species of the Wolf Spider have different patterns. Some appear not to have any markings. Some have a striped pattern that matches the look of their abdomen.

Cephalothorax – Often with a striped pattern running from front to back it is also common to see them with stripes that radiate out from the center.

Female Size - NA

Male Size - NA

Bite Info – There are no real dangerous Wolf Spiders indigenous to North America. Their bites can sometimes cause some swelling, itching and some pain, but no long term or life threatening effects.

There is a belief that the Wolf Spider can carry the MRSA Infection. I have not found absolute proof saying they can or cannot.

I do know that it is very common for doctors to misdiagnose infections as spider bites. My personal belief is that cases of a Wolf Spider biting someone and giving them the MRSA Infection is due to either a misdiagnose or the person in question already having the infection on their skin and when they are bitten, it then gets inside and becomes dangerous.

Other Notes – A common species of the Wolf Spider is very similar to the common Grass Spider in looks. They often do not have quite the same striping but the most assured way to tell them apart is by the eye pattern as mentioned above.

Wolf Spiders usually do not spin webs like most spiders do. Though they have the ability to, they often only do so to attach their eggs to their abdomen and carry them around. Once the babies hatch, they will continue to ride around on the mother’s back until they are large enough to fend for themselves.

Genus - Acantholycosa
