Question
spider one
spider one  

spider two
spider two  
Can you help me identify these spiders:

Answer
Hi Carol,

Thank you for the great photos. The first spider is a Goldenrod Crab Spider (Misumena vatia). The second spider I believe is a Giant House Spider (Eratigena atrica), but identification requires examining the spider under a microscope. If it is a web builder, then it is either a Giant House Spider or a Hobo spider. If it is a predator and you didn't find any web, it could also be a wolf spider. However, I would be willing to bet that it is a Giant House Spider. I hope this helps.

Best,
Jessica
