You may have been seeing these spiders around your home in recent years. Brown widows hadn’t been seen in California before 2003, but have since grown in number and are now quite common in Southern California. They tend to build their webs in slightly more exposed areas, so you may have found them in your backyard under your patio furniture and outdoor toys or on your fences and sheds.
What is a Brown Widow?
Brown widows are in the same family of spiders as the black widow, but are slightly smaller and lighter in color. Female brown widows can grow to around half an inch long, not including their leg span. Although they tend to be less aggressive than black widows, brown widows will still bite if they feel threatened or are protecting their egg sacs. Brown widow bites are less venomous than black widows and their effects are usually localized to the bitten area.
Differentiating Between Brown and Black Widows
Brown widows do have the representative hourglass markings on the underside of their abdomen that black widows have, but they have different coloring on their bodies. Whereas black widows have stark black bodies and red hourglass markings, brown widows tend to have tan and brown bodies with black accents and their hourglass markings range in color from yellow to orange-red. Because it can be difficult to see the underside of these spiders, the easiest way to identify brown widows is by finding their egg sacs. Their egg sacs are spherical and covered in tiny spikes.
