white death - do they change their colour to match the flower or settle on plant that matches theirs?

Question

i've seen lots of these little crab spiders this year and though they're basically white, i've noticed that no two are alike in hue, some have a pink tinge, others a yellow or green and so on.

Answer 1

Red Robins are very observant...

Yes, female (White Death) Crab spiders vary in colour from white, yellow or green; with a red stripe. They have the ability to camouflage themselves by changing colour over the space of a few days.
