Lizards of Europe: Darevskia, Rock Lizards


Introduction

The genus Darevskia is a relatively new one, having been established within the last ten years or so. Most if not all of its species were formerly considered members of the Lacerta genus, and indeed are still by some authorities. I am as yet uncertain as to the characteristics that led to the creation of this genus from the genus Lacerta, but it seems to be based on lizards from Asia Minor (including Turkey) and the Caucasus and to contain a fair number of parthenogenetic (females-only) species. There seems to be a dearth of information on the species listed here, whether on the Net or in print: only Englemann et al mention some of them (including them under the genus Lacerta). The www.lacerta.de website contains some excellent photographs.

In all honesty most UK travellers at least are unlikely to come across most of these lizards, as they are at home in mountainous regions in NE and E Turkey, Russia and the Caucasus. Indeed this remoteness may be one reason why so many of these species only have females, as asexual reproduction does not require the hunt (or wait) for a mate. This page is included mainly for completeness. Travellers to the Black Sea coast in Romania and Bulgaria might nevertheless come across D. praticola, the Meadow Lizard.
