[2] The Greek viper was previously thought to be a subspecies of Vipera ursinii, but was elevated to species status as it has many morphological and molecular differences.
Though some pattern similarity between Greek and meadow vipers can be faintly seen in some male and juvenile Greek vipers they are different, with no dark spots on their labial, lateral and dorsal sides of the head, with the exception of occipital and post orbital stripes.
It is most common at high elevations, 1,600–2,300 m (5,200–7,500 ft), of the Hellenides mountain range[4] as well as the center of the Pindos mountain range, where the limestone ground is grassy and populated with shrubs (near which most observed Greek vipers have been found[4]).
[2] The diet of the Greek meadow viper generally consists of insects, (specifically Orthoptera).
[3] In 2012, after molecular analysis of its DNA, it was posited for the first time that V. graeca was its own individual species.
