Almost certainly genus Ammophila. Does anyone have a reference that might help narrow down the species? It seems pretty distinctive. There are likely other instances of this species at the genus level in the guide. This one
seems very close.
About eight individuals of this wasp species were investigating a patch of sand, landing quickly and then taking off again. In flight they bend the abdomen up at almost a 90 degree angle, which I've never seen another wasp do. At first I thought these wasps were damselflies and the abdomen was the wings until I got a closer look with my binoculars.
