This summer, while harvesting our red clover, we came across this Crab Spider. They do not build webs to trap their prey. Instead, they rely on stealth to subdue butterflies, beetles, bees, and wasps. Crab Spiders can change their color to match the flower they are sitting on. They can become fully camouflaged in their surroundings in about two weeks.
They produce silk for drop lines and reproductive purposes. If you look closely in the photo above, you can see the silk line.
The Crab Spider used his drop line to get down safely from the flower to this rock.
