Now I look closely, you could be right. It looks like 2 bodies are there. Rather small for a flower wasp. They would be about 1cm or less, but there may be some small species.
This is a female, Catocheilus sp. Not Thynnus zonatus. These have been misidentified in many places on the internet. Refer to recent revision of Thynnid Wasps- https://mapress.com/zt/announcement/view/56
