We studied the biology of the green lynx spider, Peucetia viridans, in South Carolina, with emphasis on the selection factors that maintain extended maternal care. Nocturnal predation on the clutch was greater than diurnal predation. Chiracanthium inclusum (Araneae, Clubionidae) was the primary predator of eggs and emerged spiderlings. After producing a fertile egg sac in the field, female P viridans produced at least three fertile sacs in the laboratory. In the field, females produced a second egg sac if their first sac was lost early in the season. In contrast with other studies, spiderlings were unable to exit from about 74 % of the egg sacs without the aid of the mother
