Details of the Spiny Backed Orb Weaver
CHARACTERISTICS: The spines on the side of this spider make it unique and easy to recognize. Males are considerably smaller than females. Like other orb weavers, it creates a web that is circular in shape, only it has few or no spirals at the center of its web. Each night, a new web is spun. Late in the year, the female will lay eggs that will grow throughout winter, hatching spiderlings in spring.
