The Bee that looks like a Wasp. Or something like that.
This Cuckoo Wasp species, Nomada flava, the Yellow Nomad Bee, is a parasite - laying its eggs in the holes dug by Tawny Mining bees often, (or Andrena sp) where they develop into adults.
I saw this one holding onto the leaves of our Maris Piper plants in a rainshower, using only its jaws!
About 1cm long, it can be recognised by its brown antennae and the yellow marks on its abdomen.
