Flower Crab Spider

"The glabrous integument (exoskeleton) is cryptically coloured, taking on the colour of its surroundings. Thomisus is able to undergo white to yellow or pink colour changes depending on the flower they are sitting on. This colour change facilitates camouflage on flower ambush sites and is completed within 2 days. While colour patterns are species specific, colours can vary. Not all species have this colour changing ability as some species occur on bark or among grass seeds and thus are a cryptic brown." ~biodiversityexplorer.org
