I found this beautifull fly in a dry grassland near cultivated area. Fruit trees in the sorroundings. middle of august in Chandebrito (Nigran) Spain. 250 mts. abv sea level.
Could it be a fruit fly??

Tephritidae.
John Smit would say more. :)
I think you are using some kind of 150 mm (or 180 mm) lens? Is it correct?

As a matter of fact I use two lenses.
Usually I employ my Sigma 180 mm., together with Kenko auto-extension tubes (the three of them) and Sigma ring-flash 140 DG.
Some times, when insects are "relaxed" early morning/late evening I use my Nikkor 60 mm., with the tubes and the Sigma flash.
Obviously the 180 mm. gives me longer focusing length but then I need to use a small (housemade) monopod to assure an optimum stability.

Forgot to say, from time to time (for tiny subjects) I also use an inverted 28 mm. sigma lens, combined with one, two or the three extension-tubes and the flash, evidently.
Nevertheless I restrict the inverted lens to the minimum, you dont know how akward it is focusing with it in poor lighting conditions (be sure its a nightmare).

I know. :) I have some 4:1 magnification photos . You can see some here: (CAUTION; some images are very strong to see in bigger size :d)

I will need to get 180 mm lens from Sigma. ;) And, of course, the MPE-65 mm lens. :)
I just use one lens: sigma 105 mm ex.

Ok, back to the insect ;)
Terellia, serratulae complex.
Males are unidentifyable without examinening the genitalia.
