Huge Spider??
I live in Calvert County, Maryland and I found this HUGE spider hanging on the brick of my front porch. There is no web around and it looks like he live in a space behind the brick. Can you tell me what this might be??
Freaked out

Don’t be freaked out Autumn,
Your Northern Dolomedes, Dolomedes scriptus, is probably more afraid than you are. These are beautiful spiders which do not build a web, preferring to stalk prey. The female cares for her young in a very maternal manner. These spiders are also commonly called Fishing Spiders and Nursery Web Spiders since the only time they make a web is to care for their young. They are capable of catching small fish and are often found near water.

Would love to know what spider this is and if it should be relocated?
Thank you,
Jennifer Stevens

Hi Jennifer,
We are craving more information, like exact size and location. Our guess is that you have photographed a beautiful Northern Dolomedes, Dolomedes scriptus, or possibly the Dark Dolomedes, Dolomedes tenebrosus, in late afternoon sunlight. These spiders are related to Wolf Spiders and are sometimes called Diving Spiders. They are quite large. This is one of the larger species and is common in the North. Please do not kill your beautiful spider, and rather relocate it.

Good Morning Daniel,
I live in Soutern New Jersey and please do not worry I would only relocate her were she dangerous. Seeing as how she has been totally non-aggressive to me while taking her photos I am happy to let her raise her babies in my yard. I will be wearing shoes in the yard from now on LOL She is about 3 inches in diameter She was back on the dryer spout last night if she is there again tonight I will try to get afew more shots of her. I was also told my another bug guy that he thought it was a “fishing spider” thanx,

Hi again Jennifer,
I’m so happy to hear you will be cohabitating. Dolomedes are also called fishing spiders or diving spiders. The large ones can dive below the surface of a pond and capture a small fish. They are very maternal, with the mother spider caring for her spiderlings, allowing them to crawl on her back for several days after emerging from the eggsac she also carries.

We usually have lots of neat spiders here in South Texas, but this beautiful visitor amazed us. Never before seen on our house. Note that the trim boards are 1 by 2 inches so she is quite sizable but not as large as the Golden Orb spiders we have in abundance. We are thinking she is a “fishing spider” of some sort but the house is a half mile from the cattle ponds. What do you think she is?

White Banded Fishing Spider

Wow, JD,
That is one handsome spider. I think you are correct that it is a type of fishing spider, probably Dolomedes albineus or tenebrosus.
