Crab Spider Guarding Egg Sac, not Jumping Spider!

6-5-14 jumping spider2  077Thanks to the sharp eye of Peter Hollinger, a Naturally Curious reader, the spider in this photograph can correctly be identified as a crab spider, possibly in the genus Xysticus, not a jumping spider! The eyes of this crab spider, while impressive, are not nearly as much so as a jumping spider’s. In addition, this crab spider’s four front legs are relatively longer than those of a jumping spider’s. Neither of these types of spiders spins a web to capture prey and both stay with their egg sacs to guard them. Thank you, Peter!

    Mary, I’m eager to share this info with my grandkids who have great respect for mama spiders after hearing and seeing CHARLOTTE’S WEB. One of my morning treats, just after coffee, is savoring NATURALLY CURIOUS.

  2. I love these little spiders! Their alertness (all those eyes?) and spritely actions fascinate me. We have the black/white jumpers (Phidippus audax) on our deck and often our meals have these guests showing up to make the rounds. I find them charming.

    Dear Mary,
    I applaud you for your instant corrections of the few honest mistakes in your identifications…makes me smile because of course we naturalists always make mistakes. It’s good to own up. I really love my daily nature fix. Many thanks. That beaver with quills in its nose was remarkable.
