Crab Spider

The Oxytates are masters of ambush and disguise. They stalk their prey at night, from an ambush position on a grass stem or from the underside of a leaf. They can sense the vibrations caused by invertebrates moving on the leaf's upper side, and quickly pounce on the victim. While in ambush on twigs or grass, the short hind legs hold onto the stem, while the long anterior legs are stretched forward-as seen in the third picture.
