Question
Yellow Crab Spider
Yellow Crab Spider  
Evening Eric,

I saw you've been busy today with questions.  Found this yellow crab spider out on my passion flower today.  I thought it might be a whitebanded crab spider but am having second thoughts,  I know crab spiders can change color over time to match the plant  they are on.  I guessed a Misumenoides formosipes.  Probably just a female flower spider that changed color.

Answer
Ralph:

I believe this is a crab spider in the genus Mecaphesa .  They tend to be much "hairier" than other flower crab spiders.  This one is not as hairy as many, but still moreso than a Misumena vatia or Misumenoides formosipes .  Mecaphesa is also more common, in my experience anyway.
