Spiders of this genus are rather large and have a smaller number of predators. Its web can be as large as 8 feet in diameter making it one of the largest orb weaver webs in North America. Mating occurs in the fall when the female deposits egg sacks. Adult females have an abdomen a little bigger than a marble. During the day, the spider leaves the web (where she would be an easy target for predators) and move up one of the guy lines to some curled leaves where she has fashioned a hibernaculum, her little daytime resting place. The females spines are either black or red, but the males do not have spines. It is one of the largest spiders found in North America, with an average body length of 3 to 4 inches.

This web type is called a nursery because the spider will rest on its web at night. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs. Mud dauber wasps are known to see young spiders as this genus as good prey. These types of Spiders in Louisiana do not make webs but catch prey by jumping on them with their long front legs. The building of a web is an engineering feat, begun when the spider floats a line on the wind to another surface. Though they can look scary, they are mostly docile and only bite if cornered. The spider species Micrathena mitrata, commonly called white micrathena, is an orb weaving spider. These types of Spiders in Louisiana have a white, flat abdomen with brown stripes running the length of it. She rapidly assesses where it is and quickly moves to wrap and otherwise immobilize it. Passive hunters lie in wait and capture prey as it approaches. Spiders of this species prefer to immobilize prey by injecting venom, unlike many orb weavers that wrap caught-up insects in silk. They are typically dark brown with a lighter tan stripe on their back and can grow up to 8 inches long from leg tip to leg tip. The top of the abdomen is generally of a lighter color.
