    Nursery Web Spider - (Pisaurina mira)

    The female Nursery Web Spider is a dedicated parental caretaker, usually seen with its egg sac until the spiderlings hatch.

    Staff Writer (8/23/2017): 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.

    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
