Spined micrathena orb weaver spider

Females, the only sex to build webs, are 8-10 mm long. Their white or tan bulbous abdomen has 10 spines. Males are around only half the size of the females, 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.
