Male wasp landed on the grass with female wasp attached to his abdomen. She remained attached for several minutes as he walked around, and it kind of looked like she might have been feeding from his abdomen (as documented in Life in A Southern Forest - https://southernforestlife.net/happenings/2020/10/flower-wasps). He bubbled nectar while she was attached. He then flew off, leaving her to walk off on the ground. I also have a video of their behaviour, but it was too large of a file to attach here.
