Older unidentified observation
29/04/20
Shrewsbury, UK
Limited detail in photos...but possible for it go anywhere?
Suggestions on iNaturalist so far = Actia lamia or Paracraspedothrix.

Bend in M-vein seems extremely faint, but visible in this otherwise rather useless image :)

If in grassland Paracraspedothrix.
If in wood near mushrooms on wood: Phytomyptera.

Ok, thanks Theo.
This one was in town centre, photographed on stone.
I think on architecture - a church/nearby wall between park and graveyard.

Phytomyptera needs Ganoderma mushrooms or similar.
So Paracraspedothrix seems more likely …

In terms of existing records, there would seem to be three options:
Paracraspedothrix montivaga
(only known member of genus in UK - previously recorded nearby in town)
Phytomyptera cingulata
(previously recorded nearby in town)
Phytomyptera nigrina
(previously recorded in county)
The other Phytomyptera listed have little to no actual records in country.

I don't have to mention the pictures are of poor quality. In Phytomyptera, the apical cross-vein (when present) is distinctly concave in apical half. I don't see that here.
So I am pretty convinced this is Paracraspedothrix montivaga.
N.B. Craspedothrix is a junior synonym of Phytomyptera !

Yes, terrible quality.
Early days in terms of my diptera recording.
Better equipment now, so hopefully these days are largely passed.
But thanks for the detailed input Theo, all very much appreciated.

Well, it is a small fly.
