Hi,

I've a couple of Hydrellia from different UK sites that I have dissected but can't work out based on Martin Drake's draft key. They both seem somewhat near to H. mutata based on external morphology and genitalia but seem quite different from each other based on their genitalia.

A long shot but does anyone recognise them based on their genitalia?

Both from rich wetlands, first in the Nofolk broads and second Amberley in Sussex.

Many thanks,
Sam
