As members of the Nursery-Web family, females will lay their eggs on a silken mat and wrap them up into a small ball. She will then carry the egg sac in her jaws as she looks for a good place for them to hatch. She will build a web and attach her egg sac to it, then stand guard until the spiderlings emerge. Hundreds of spiderlings can hatch and they eventually disperse from the nursery on their own silken threads.
Fishing Spiders get their name from their hunting behavior and occasional food source. They are adept at ambushing insects and other food items on land, but they are also able to submerge their bodies just under the surface of calm water and hunt for small fish and tadpoles. The bristly hairs on their body trap air bubbles that they use to breathe while underwater, waiting for something to swim by. They have been known to stay submerged for more than 30 minutes at a time when hunting in water. They are also able to eat insects skimming or treading on the water's surface above them.
Fishing Spiders are found near bodies of water. They may also venture into nearby woods for terrestrial hunting. They are active during the summer months.
