“Phidippus regius is a common spider in peninsular Florida. The first impression made upon the casual observer is of a moderately large, black, hairy spider; to the uninformed, this impression leads naturally to the conviction that the spider is a black widow. The black widow, however, is a globose, shiny black spider with long, spindly legs that is not noticeably hairy at all. Jumping spiders are harmless, beneficial creatures. The larger species, such as P. regius, are capable of delivering a painful bite, but will do so only if held tightly. The bite itself causes a sharp stinging sensation which subsides in a few minutes and requires no treatment. These spiders are easily tamed and can be induced to jump back and forth from hand to hand.”
Yes, that’s an egg sac she’s protecting.
