You can look, but don't touch the Spiny-backed Orbweaver spider. Those thorns help keep predators at bay.
The spines on the side of this female spider make it unique and easy to recognize. Males are considerably smaller than females and they lack the spines. There are a variety of species in this genus and colors vary.
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 to catch small insect prey. The spider stands up-side-down on the web.
Late in the year, the female will lay eggs that will grow throughout winter, hatching spiderlings in the spring. The oval-shaped egg sac is near the web, usually hidden underneath leaves. It may be white, green or yellowish, but it is woven of the spider's silk.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
