Crab Spider (Misumena vatia), an ambush predator, getting into position on a Phantom Orchid (Cephalanthera austiniae) flower. I was setting up a macro shot of this flower when this well-camouflaged spider crawled up the stem, climbed into the flower and prepared to ambush flies that landed on the orchid. The elapsed time in this sequence was 1 minute and 40 seconds. Yosemite National Park. Tuolumne Co., Calif.
