Hydrophoria lancifer query

Could anyone confirm suggested ID for this fly is right, or perhaps correct my error. Hoping to sort out some of the common species that I tend to ignore.

Thanks, John

Muscid fly ID querry

Submitted by BINGHAM on

Can anyone help ID this Muscid. Found in Jan 2020, north Worcestershire, wooded churchyard. I'm sure it's a common species but having trouble! Will post info on iRecord if identified.

Thanks, John

Phaonia/Helina or Anthomyiidae female?

This female Muscid - either Helina or Phaonia (I think Phaonia, but can't be sure) has pale fine hairs on the underside of the scutellum, which is an unusual feature, but I'm damned if I can determine which species it is! Can anyone suggest a species, or what to check? It has two PDs on the hind tibia. The abdomen in the image is darker than it should be, due to discolouration

Help with family please

I've got completely stuck with this acalypterate fly. It has stout fore femora and a longish proboscis that folds back on itself. The palps look quite distinctive as well. Two costal breaks. Caught in a flight interception trap in an old damson orchard in Buckinghamshire in July 2019.

Can anyone point me in the direction of a family please?

Identification help required

Submitted by sifolinia on

I've been having difficulties with this specimen, so after several hours feel I should get expert help! The discal cell is reminicent of Dolichopodidae, but it's not metalic and I can't get it to key out satisfactorily. Quite frankly, I suspect it belongs in another family, but I can't work out which.

Total length including wings is about 4 mm. It was swept from Trewalkin Meadow, a wet lowland meadow near Talgarth, Breconshire, on 25-7-2018.

? Xanthandrus...

This lady keys out to Xanthandrus comptus, but has all yellow legs (barring only the hind metatarsus).  Otherwise the match is sound - elongated stigma, tergites 3 and 4 with square abdominal spots touching the front and edges of the segments, black scutellum).  But the legs are exceptionally yellow.  Any ideas?
