Jumping Spider

Yellow Spider
I found this spider in Northern Utah. I have lived here for 30 years and have never seen a fuzzy, yellow-backed, yellow-fanged spider before. Nor has anyone else I have asked. I have attached some photos. The spider had many babies in another section of this plastic cover. Any information you have is appreciated. Thanks,
Jeremy Smith

Hi Jeremy,
This is a Jumping Spider, probably Phidippus apacheanus according to some images on BugGuide. This is a yellow color variation of a variable species. Jumping Spiders in the family Salticidae are active hunting spiders that do not build webs. They have excellent eyesight. They are not a threat to you.
