Comments & ID Thoughts

Anyone know what kind of spider this is? It seems to be female, she has her egg sack with her. She is under the patio cover just sitting there with the egg sack.

Hi, she looks like a Fishing Spider. I can’t tell which species from the photo. We have reports of three species in your state in genus Dolomedes. It is also possible that she is a Nursery Web Spider. They are related to Fishing Spiders. The characteristic trait is that she is carrying her egg sack under her with her fangs and palps. Wolf spiders carry the sack under them too, but at the posterior end of the spider. They are thought to do this to protect the eggs from parasitic wasps.
