Southern Black Widow (Latrodectus mactans)

This southern black widow was found at Sand Prairie Conservation Area in Scott County MO. Quite unusually, she had built a web in the open within the tallest branches of a Polygonum americanum (American jointweed), where she had just dispatched a Dielis plumipes (Feather-legged Scoliid Wasp).

This southern black widow female was found wrapping up her prey, a feather-legged scoliid wasp at Sand Prairie C. A.
My shadow cast as I took photos caused her to head for cover.
I also found a male southern black widow moving about the boundaries of the female’s web.
