Please identify this fly common in a zone of NE corner of Spain (Catalonian pyrenees) with a entomofaunae composition with a very "french" style (various kinds of dragonflies and grashoppers relatyvely common in France but rare, very rare or very restrained in Spain). Photographed last week. Big size, as a Tachina fera. Habitat: marshes with many rushes? (Phragmites australis).

The small antennae & slightly shaded rm vein remind me of Trixa but let's wait for Theo because I am sure there are more alternatives in the south :)

It's possible ... I never see them here in the UK though so I am not very familiar with them :D

The topcel seems closed and the crossvein r-m is darkened.
So I think it is Estheria picta, which I know to be common in the Pyrenees around this time.

OOOOOPS!!!!!!!!!!!!!!!!

Now I saw that the second image is a completely different fly from a different place that I've pghotographed around the same days. I's bigger tha supposed Estheria picta and with more long legs, and was photographed in Plan, Huesca, and collected (two exemplars at least) by Jorge Mota Almeida.

Good to know.
Maybe different fly, but still can be same species. Legs are longer in males Dexiini.
As said, E. picta is quite common these days in the Pyrenees.
