Goldern Hoverfly Callicera spinolae

The Golden hoverfly (Callicera spinolae) is a rare species of ancient woodland and parkland in the south east of England. The larvae develop in wet rot holes so the hoverfly prefers old trees with snags or a complex structure of branches, which is more likely to produce the right microhabitat.
