Nursery Web Spiders
Posted on November 11, 2019
These spiders are named for their reproductive habits. Mother spiders carry their egg sacs using their mouth parts and then attach the sac to a plant and build a nursery web around them to protect the emerging spider-lings. Common nursery web spiders in Massachusetts and other parts of New England include the dark fishing spider (Dolomedes tenebrosus), nursery web spider (Pisaurina mira) and six-spotted fishing spider (Dolomedes triton).
