Flowers spiders have short, wide, flat bodies. The first two pairs of legs are larger than the hind legs and held open so that the crab can easily hold its prey. Females are 6 to 9 mm long, males are smaller: 3 to 4 mm. The female is light colored: its back and legs are white or yellow with darker sides, and reddish markings on its abdomen. The male is darker: reddish brown in color with a white spot above the eyes. These colors are variable, and the spiders can change color to match the flower they hide on. Both sexes have small, venomous fangs.
Range length: 3.0 to 9.0 mm.
Other Physical Features: ectothermic ; heterothermic ; bilateral symmetry ; venomous
Sexual Dimorphism: female larger
