Sharp prickles around the squat abdomen of the Spinybacked Orbweaver spider keep predators at bay.

The spines on the side of the female spider make the Spinybacked Orbweaver unique and easy to recognize. Males are considerably smaller than females and they lack the pointy spines. There are a variety of species in this genus and abdomen colors vary from red, orange and yellow to white and ivory. Spines are black or red. All have wide abdomens that give the body a crab-like resemblance. This kind of spider is sometimes called a Crablike Spiny Orbweaver.

Like other orb weavers, it creates a web that is circular in shape with only a few spirals at the center of its web. Each night, a new web is spun to catch small insect prey. The spider sits up-side-down on the web. Late in the year, the female lays 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.

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the Spinybacked Orbweaver may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America. States/Territories shown above are a general indicator of areas inhabited by the Spinybacked Orbweaver. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
