There are several species of Neoscona and Araneus orb weavers in Missouri, and some of these spiders are difficult to distinguish. They tend to have camouflage patterns, and all make the characteristic, delicate, wheel-shaped "orb" webs as nets for catching prey. More

Barn Spider (Spotted Orb Weaver)

This “barn spider” is probably Neoscona crucifera, also called Hentz’s orbweaver and spotted orb weaver. It’s a widespread species that commonly builds its webs in woods and on the eaves of barns and other structures (including houses). The female takes down her web each morning, hides in cracks and corners during the day (as shown in this picture), and spins a new large, round web at dusk. This individual built her web next to a dusk-to-dawn porch light each night for several weeks one late summer, taking advantage of the host of flying insects attracted to the light. More

Black Widow Spider

Latrodectus mactans & Latrodectus variolus
The glossy, black-bodied female widows have distinctive red spots on the underside of their abdomens. In L. mactans this spot often is shaped like an hourglass; in L. variolus it is not. Faint red or white spots may also appear on top of the abdomen, as they do in males. Only the sedentary female black widow is capable of inflicting a potentially dangerous bite; the wandering and seldom-seen male is harmless. More
