American Nursery Web Spider
Pisaurina miraAlso known as Nursery Web Spider
American nursery web spiders are agile, active hunters that stalk insects through fields and tall weeds without building capture webs. During the mating ritual, males often bind the female's front legs with strands of silk to avoid sexual cannibalism. Before spiderlings hatch, the mother constructs a protective silk tent around folded leaves, fiercely guarding hundreds of offspring until their first molt.
