Brown Widow Spider
The brown widow spider is one of the most dangerous spiders in New Mexico. Although it is considered one of the least dangerous species of widow spiders in the United States, its venom is still potent and can cause burning, swelling, and muscle spasms if a person is bitten.
Brown widow spiders can be identified by their black or dark brown color and orange or yellow hourglass marking on the underside of the abdomen. They build webs in secluded, protected sites such as under rocks, in woodpiles, and in other sheltered areas. Female brown widows are not aggressive and will usually withdraw to their retreats rather than attack when their web is disturbed.
