Gymnosoma rotundatum, sometimes referred to as a ladybird fly, is a small 5-6mm long fly. It has a dark thorax, golden in males, and a globular orange abdomen decorated with dark rounded markings along the midline.[4] The base of the wings are yellow-brown.[7]
Behaviour
The larvae grow as parasites of shield bugs in the Pentatomidae family. In Britain, the species is often recorded in warm dry sites, where it visits a range of open shallow flowers.[8]
