Saw two different spiders on a nest, what is the second one?
First photo is from July 9th, I found the nest & egg sac then what I presumed to be the mother (jumping spider) appeared & seemed to be watching over the sac. I have monitored the sac (on a lawn chair in my backyard) since the 9th but haven’t seen the jumping spider since then. Last night (July 22) I checked on them & they have hatched but this spider that I’m having trouble identifying was now kind of guarding the nest. What is this spider & is it trying to eat the babies or was the jumping spider out of its territory?
