Probably Steatoda grossa.
Hubby thought female black widow, I disagreed. He thinks everything is a black widow…what do you think the weird round spot on the back is? Thanks!
Many false widows as well as other spiders, have dimples on the dorsal side. Usually 4. These are points of attachments to the exoskeleton by the spiders heart and digestive tract.
Thank you that’s super interesting!
I looked it up and agree
Steatoda grandis is a possibility in Colorado. https://bugguide.net/node/view/6926 Her abdominal shape looks like S. grandis, but her dark black color looks like S. grossa.
