This digger wasp was found over the weekend at Crymlyn Burrows, inspecting some drift wood along the extreme strand line (at the base of the dunes). It looks close to images I have found of Ectemnius cavifrons, but the reality is that its identity cannot be called safely from the photos I took, not by me at least!
Digger Wasp (Ectemnius sp.)
Another invertebrate that I didn't capture on camera, but saw briefly, was a Coelioxys sp. also known as Cuckoo bee or Sharp-tailed bee. This parasitic species of bee lays eggs in the nests of Leaf-cutter bees.
