The orb-weaver of the Araneidae family, the Larinioides cornutus, commonly known as the Cornutus furrow, is a species of spiders with its habitat mainly in North America. This spider is also known as a furrow orb spider and a foliate spider.

These arthropods build their web in the porches of urban houses and moist places like under the roof and near your bathroom pipes. They build their web close to the ground, and every night, they consume their web and a new web is built in the evening the next day. Orb-weavers live independently since their birth. However, they might be hunted and eaten by birds especially the black-and-yellow mud daubers.

The mating season of furrow spiders is mainly spring and fall. The female spider creates a silk cocoon in the foliate for the eggs and the female resides in the cocoon. they emit pheromones to lure the male in their web, which the male can sense with their chemoreceptors. Males fertilize the eggs of the females using their pedipalps, after which the egg sacs become yellow. The male lives with the female spider during reproduction. The females produce three to five yellow egg sacs, and they remain there after hatching for two to three months before they disperse.
