Thank you for trying to find the ID. I don’t think I could say something is Anyphaena aperta. Some spiders can only identified by an expert taxonomist with a dissection microscope. Our reference photo came from a spider expert who has a taxonomist who confirms the species for him. I get the impression that it is common in Entomology for researchers and explorers who specialize in habitat or behaviors to work with an invertebrate zoologist that specializes in anatomy. That’s a long way of saying, “it’s complicated.” On citizen science websites, like this one, we do the improper science of… Read more »

Possibly Anyphaena celer, there’s a couple other similar options. A. aperta is found on the west coast.
