Goldenrod Crab Spider (Misumena vatia)
is a species of crab spider found throughout North America. This spider can be one of two colors, yellow or white, which they can change between depending on which flower they are on. This doesn’t happen through chromatophores like most color changing animals do, this spider instead secretes a yellow pigment on the outer cell layer of the body which then gets transported to the lower cell layers so that the inner glands become visible. This spider like most is dimophic as females are two times as large a the males.
