Title: Plant identification for Beeville, TX
Answered by: Nan Hampton
Thank you for that excellent suggestion! Why didn't I think of that myself. When I read "small black and white dotted flower", for some reason it translated to my brain as "white flower with black dots" but it could just as well be "black flower with white dots". I think you may have nailed its identification as Aristolochia erecta (Swanflower). The text on this species page under GROWING CONDITIONS says: "Swanflower is a trailing grass mimic, presumably to evade female Pipevine swallowtail butterflies looking for a good place to lay their eggs." It all matches the description above.
Here are more photos from the School of Biological Sciences The University of Texas and Earthlight Imagery. I'll be sure the person who wrote the question from Beeville, TX sees this question and answer.
