Hello again Tony.
All the pictures I see of Scaptomyza graminum shows gray Scutum with narrow dark center stripe.
This is reddish brown with broad diffuse center stripe - it's just variation or ...?

The photos don't show all the key characters. However, it's got four rows of acrostichals and the apical scutellars are shorter than the laterals, so I'd still go with
graminum, but it would be good to get an expert's opinion. Paul?

A proper lateral view would reveal a lot...

Sorry, not
Hirtodrosophila cameraria. From memory, I think 4 rows of acrostichal setulae would be wrong. However, 2 ventral branches on the arista and the presence of a pre-apical bristle on the mid leg is certainly wrong. Also the overall 'feel' of it is not Cameraria (too narrow / lightly built)
I would certainly go with
Scaptomyza (which I don't know well, but probably
not pallida). Apparently anterior dorsocentral closer to suture than to posterior dorsocentral and only 2 katepisternal setae would confirm scaptomyza.
Another possibility might be
Lordiphosa (4 rows acrostical setulae), but again katepisternals would need to be seen

always to take a lateral pict!
Drosophilidae indet. is the only thing I´m sure of now :D
