The female Nursery Web Spider is a dedicated parental caretaker, usually seen with its egg sac until the spiderlings hatch.
The Nursery Web Spider derives its name from the good care it takes of its egg sacs. Females carry the sac with their fangs and build a web for it in high weeds or low shrubs, suspending it inside of a leaf. The female then guards the leafy nursery and her eggs until they hatch.
This spider does not spin a web to catch prey. It is an ambush predator and uses its silk for other purposes. Males look slightly different than females. Both genders eat insects and other invertebrates that they are able to catch and subdue.
