8 mm long orbweaver. The first photo is the ventral view showing the spider's spinneret, or silk-spinning organ. The only web-building members of the species are the females. Females are 8-10 mm long. They exhibit a bulbous abdomen with a total of ten spines. Males exhibit a fair amount of sexual dimorphism. They tend to be around only half the size of the females. Also, they have fewer spines, a flatter abdomen, and a slightly lighter tone. Although males can produce silk, they mostly use it in the mating ritual, which frequently also proves fatal.
