The female White-banded crab spider has the ability to change color. She uses this super power of cryptic coloring as camouflage, changing between white and yellow depending on what color flowers are in her territory. She does this by secreting a liquid yellow pigment into the body’s outer cell layer which is normally white. This color change cannot take place immediately. In fact it takes days, sometimes weeks.
