Spider Identification

We can help you identify your spider. Did you find a spider that is nothing like any you have seen before? Did you look through the list of common spiders for your state on this site and din’t find any information?

Let us help you identify your spider!

Upload a picture of your spider as a comment to this post below in the “Leave a reply” section at the bottom of the page. Along with the photograph, please add the following information:

  1. Description of the spider (helps with the identification but is not mandatory)
  2. City and U.S. State where the spider was found
  3. Your name how you want to be credited on our website

By uploading a picture, you are giving us permission to use the picture on this site. Please only upload pictures you own the copyright to. Do not upload pictures taken from other web sources without proper crediting. Any pictures we use, we will place your name and city where it was found beneath the picture as the photographer.

When uploading your picture, you are required to enter your email address. Your email address will not be posted publicly. As soon as we have found an ID for your spider, you will be notified by email to the email address provided by you.

Taking the perfect picture of your spider

The more detail can be seen, the better. It is easiest for others or for us to identify your spider if the photograph is taken from the top of the spider. If both body parts, the colors, and the markings are visible, it will go a long way to getting the spider correctly identified. If you have a good camera and are not afraid to get a good close macro shot of its eye pattern, that can also help immensely. Some species can only be distinguished by a close look at their eye patterns.

Please upload the picture as its own file to the comment form below. Our upload form allows all standard image files up to a size of 15 MB. It is not possible to upload .zip files or more than one picture per upload. If you have more than one picture of your spider sighting, please upload them separately and copy the description text including the location along with it.

If for some reason, the upload form doesn’t work or you prefer that your spider picture is not published publicly, you can send us an email with the information to [email protected] and we will get back to you with an ID via email. However, we do prefer that you upload your picture in the comment form below as it will benefit all our readers.

  1. We see a number of these indoors — this one was on my desk, on 8/21/20. Its leg span is maybe 3/4″. We live in Warren, RI.

  2. Going off the eye pattern and the hairs, I think this is a Mecaphesa, possibly Mecaphesa celer, which is found in Utah. Am I correct? It was found on a sunflower in my yard on 1 July 2020, South Jordan, Utah

    Yellow Crab Spider Misumena vatia, Daybreak, july 2020 found in Utah

  3. Found it dead in our basement today in Richmond, Virginia, covered in webbing. It is hairy. Its body is about 1” without its legs measured.
