I'd say this one was
Hydrellia, Nigel.

Thanks Tony- Can I check:
The lunule is well above the top of the antenna (as one would expect for Hydrellia) but the distance between the lunule and the anterior ocellus is less than the distance between the two posterior ocelli. Is this a case of an exception to the rule, or is it best just to look for the general placement of the lunule in relation to the antenna?

In
Hydrellia the distance between the top of the lunule and the anterior ocellus is less than the distance between the outside edges of the posterior ocelli. I think that's what you just said. So it's
Hydrellia. Perhaps worth checking the wording in the key you're using? ;)

I think this is one of those borderline cases where the fly has not read the script! I'm happy it's Hydrellia, although the ratios described are not quite right, I can't see that it can be anything else. Thanks for your help.
