We found this spider in a towel in our backyard and weren’t sure what it was. Can you help??
This is a juvenile Western Black Widow. This female will eventually lose the intricate markings and mature into a glossy black spider with a red hourglass marking on the underside of the abdomen. If you flipped this juvenile over, you would see the hourglass. You may compare your spider to this image on BugGuide.
