In huntsman spiders, in the family Sparassidae, prolonged subsociality is a form of spider sociality in which a single adult female shares a retreat with multiple generations of her offspring. Depending on the species, the spiderlings will stay with their mother for five to 12 months. During this time, the siblings tolerate each other and even share captured prey. Shown here is an adult female spider in the genus Delena at left with three different clutches of young. (Photo by Linda Rayor, Ph.D.)
