Neomyia cornicina. ;)
Some quick tips : Lucilia : more than one postsutural acrostichal, mid tibia with at least one strong ad, genae not metallic green.
Chrysomya : stout flies with poorly developped setae on thorax and abdomen, and (european species, with a dark stripe on hind margin of tergites).
Other metallic green muscid : bent of vein M is smoother (not angular), and can have hairy eyes (never in Neomyia or Calliphoridae).
