Big Ball of Joy - _TNY_9856
When you see spiders carrying around an egg sac, it is either a wolf spider (Lycosidae) or a nursery web spider (Pisauridae) and it's quite easy to tell the difference.
Wolves attach their egg sac to their spinnerets under their abdomen and when the spiderlings hatch they climb up on top of mom's abdomen and hitch a ride there for a llittle while.
Pisauridae has chosen a slightly different solution as mom's like this nursery web spider (Pisaura mirabilis) show. They instead carry their egg sac using their chelicerae and when it is time for the slings to hatch, she constructs a nursery web (the family name is kind of a giveaway there) and then stay in it to protect her eggs and subsequent young ones.
