Xanthogramma pedissequum

An eye catching hoverfly with an unusual life cycle

Xanthogramma pedissequum is an eye catching hoverfly on the wing from May to September.

It’s an uncommon hoverfly, with records in the National Biodiversity Network Atlas suggesting a quite localised distribution throughout central and southern England.

According to Wikipedia, the larval stages are associated with Black garden ants (Lasius niger) and Yellow meadow ants (Lasius flavus) and probably feed on ant-attended root aphids.

The photograph was taken during the last week of April in a hay meadow adjacent to the Thames at the Earth Trust, Little Wittenham.
