Platanthera ciliaris (Yellow Fringed orchid) with small spider

This morning, I went out into the front yard to check the bog garden. I saw a pair of Platanthera ciliaris or Yellow Fringed orchids just beginning to bloom. On the lateral sepal of one of the orchid flowers was a very tiny spider. I think it is a jumping spider of some type, but I don't know the botanical name. Any help with the identification will be appreciated...

Thanks to Lou Orr and Lepanthes2010, I believe the spider to be an immature Phidippus audax or Bold Jumping spider of the family, Salticidae.
