Steatoda Bipunctata – Rabbit Hutch Spider

The Steatoda bipunctata, commonly called rabbit hutch spider is a black spider found throughout the United States. It comes from the same family as the feared black widow spiders and is often confused with them. The bite of a rabbit hutch spider is not dangerous for humans. It is from the same genus as the Steatoda triangulosa spider.

Description

Most often, the S. bipunctata is brown and has a thin, light colored, stripe that curves around the front of the abdomen as well as running down the middle of it a short ways. The abdomen on this fellow is not always as glossy as the others.

The Rabbit Hutch Spider is also known as the False Widow because it is nearly the same size and has a similar body shape. When they are black, they are often confused with the Widow, except they do not have the tell-tale red hourglass marking on the bottom of their abdomen.

Size

The Steatoda Bipunctata are one of the smaller Steatoda, as the females only grow to about 5/16” (8 mm). Including the legs that would be a little more than a half inch. Maybe as large as 5/8” (16 mm).

Bites

There is extremely little information available on the effects of a bite by the Steatoda bipunctata. A large reason for this is because there are so few bites by them.

The S. bipunctata is a very timid spider and only bites when it absolutely needs to. In some articles I found on-line, it is reported that they cannot penetrate the human skin. I read one article saying that it is very rare to be bitten by them but when they do it is no worse than a bee sting. One thing for sure, of the different Steatoda, the Bipunctata seems to be one of the least dangerous.

  1. Found in a garage in Farmington, CT. I believe it’s a Rabbit Hutch (False Widow) but checking with you to confirm.
    Black with dark brown spots on top and a brown field on bottom. If you need more pictures, please email me. Thanks

  2. I live in western Washington. I found a Rabbit Hutch Spider indoors. Female. She was carrying her eggs on her sides, (sorry I didn’t have a camera), they were tiny, clear, blueish -white eggs, like bubbles. Adorable. It looked like she had gotten out of a bubble bath.

    1. Hello Cal, thanks for getting in touch! Yes, the body shape and the longitudinal stripe suggest that this is a female rabbit hutch spider.

  3. Please verify that this is a rabbit hutch spider. I live in Washington, near Tacoma. It was on my bedroom wall tonight. Thank you.

    1. Hello Linda, no, this is not a rabbit hutch spider. It appears to be some species of ground spider (Gnaphosidae). They are not medically significant.

  4. Hello! This spider is in my bathroom and am wondering if this is this kind of spider you talk about above? We live in Montana and I thought it was a black widow but I don’t think it was so wondering if anyone here can confirm what it is?? This picture is blown up it was pretty small in a web behind my downstairs bathroom door 😱 this picture is of its abdomen..it was upside down hanging in its web.

      1. Hi,
        I found this beauty outside in an old planter in Merritt BC. I was just wondering if you could tell me what kind of spider it is? I’ve seen a lot of spiders and never have I ever seen one like this. (This is the underside)
        Thanks for your help,
        Lingling
