A couple of these striking-looking flies – black with sunburst spots on the wing bases – were basking around the ivy flowers in the south-facing shelter of the walled garden at RSPB Saltholme.
The female Noon Fly, or Noonday Fly, Mesembrina meridiana, lays a single egg on horse or cow dung. The larva is a predator, feeding on other fly larvae in the dung.
