Hello,
I took this female Rhamphomyia off a Narcissus flower on 28 March - UK grassland and pools habitat.

Using Collin (British Empididae) I have keyed it as R sulcata, but the labrum is very long? Can anyone comment?

Correct. The labrum is extended, making it appear very long.

Ah, is that what happens then? Thanks for the tip and confirmation of ID. Collin guessed that the flight period is May-June, clearly it flies earlier than that.

I can fly considerably earlier than that (as you have noticed) but generally they start getting out in numbers in the second half of April, peak early-mid May.
