The arabesque orbweaver is a common orb-weaving spider in Missouri. The coloration is quite variable, ranging from tan to yellow, orange, rusty, brown, or blackish brown, but the slanting, not horizontal, dark marks on the abdomen help to identify it.
It is one of the common members of Missouri's spotted orbweavers (in genus Neoscona). The different species in this group can be difficult to distinguish. Neoscona species are spiny-legged spiders that all tend to have camouflage patterns, and they all make characteristic, delicate, wheel-shaped webs to catch prey.
During the day, the female arabesque orbweaver hides in a retreat such as a rolled-up leaf. At night, she sits in her wheel-shaped web with the tip of her abdomen protruding through an open space in the center of the web.
