These flies were out and about during January this year, and make excellent close-up subjects. I haven't seen any around for some time now. Must not like the cooler weather.
Their bodies exhibit iridescence, similar to some other flies and beetles. They are very attractive critters (as far as flies go!).
Incidentally, there are differences of opinion as to what constitutes macro versus close-up photography. I choose to call my shots macro regardless of whether they are technically macro or close-up primarily coz I am using the macro function of my camera.
