Some information:

General:This species is a sit-and-wait predator that captures pollinators as they visit the inflorescences on which the spider sits. The spider has strong front legs which are used to seize prey. The female spider is much larger than the male. The length of females is 5.0–11.3 millimetres (0.20–0.44 in) and the length of males is 2.5–3.2 mm (0.10–0.13 in). The pattern of markings on females is variable and the overall color of the body can change between white and yellow dependent on the color of their surroundings. The color pattern for males, which does not change in their lifetime, differs from females in that the four front legs of males are dark brown and the abdomen is gold. The spider can be found throughout the United States. Males search for sedentary females within a heterogeneous habitat.
