Both Graphomya maculata - the colour patterns and the absence of an anterodorsal on the mid tibia distinguish them from the less common G. minor.

Not about ID ... Indeed you have wonderfull photos with a level of detail rising up to the moon. But then I noticed that almost all your flies are siting on the underside of leaves, and all very similar leaves ... and I don't often see plants with the underside of their leaves facing up (or it wouldn't be underside  ) ... and I guess that not so many flies have the habit of landing upsidedown on leaves ... and I take by experience that it is hard to photograph upsidedown ... and most of them don't even have their pads firmly on the 'ground'.So the detective in me says you collect the flies, kill them neatly and without damage and then use the very cooperative models in some improvised (or not) studio with the underside of leaves as background. And it is an impressive technique with amazing results. Am I close to the truth?

Am I close to the truth? Hello Armando, Thanks for your compliment. Just as crex mentioned, you'll find some answers to your questions if you visit the link provided. Yes recently I use mostly a leaf underside as a (more or less natural) background, I just discovered that overall lighting improves then (with my camera setup) since undersides are often more light-coloured than uppersides. I prefer leaves of Cornus alba and Philadelphus coronarius, they are flat enough, not too hairy, and they don't wither or become deformed too soon, maybe just have too many veins which is even more visible on their undersides. As regards the specimens' more general state, I assure you that all of them are alive unless specifically indicated otherwise. |
