Chloromyia formosa: the broad centurion soldier fly

Post date: Monday, 29 February, 2016 - 00:00

If you take the trouble to look you will find this little fly, the broad centurion soldier fly (Chloromyia formosa) sunbathing on the leaves of hedgerow plants in summer. They are also often seen feeding on the pollen from hogweed in late summer. It is a wonderful metallic green that glistens in the sun. The male has a bronze sheen to the abdomen whereas the female has a more bluish colouring.

One of a family commonly known as soldier flies because of their bright colouring supposedly resembling military uniforms this one has been named the broad centurion. It has a flattened body with a square 'tail' end. 

Eggs are laid on leaves and the leaves fall in autumn where the larvae emerge the following spring and feed on leaf litter and other material in damp ground. This means they have a preference for wetter areas around woodland edges and hedges which have ditches and that is where you find the adult fly sunbathing.
