Hello, what is this insect? It has one pair of wings, the colors on it are black and yellow. I just thought it was odd that it’s abdomen was so skinny. It tends to fly quite slowly and it whirs whilst it flies. It is a wasp of some sort? Although the patterns of black and yellow are not striped, looks more spotted.
There is a reason “wasp-waist” has been used to describe a femine physique that has a tiny waist and awesome curves. Your Mud-Dauber from the genus Sceliphron also possesses a textbook thread waist. The species does have two pairs of wings.
