The Balkan green lizard (Lacerta trilineata) is a species of lizard in the family Lacertidae. It is the most widespread of the Balkans lizard species. It is found in Albania, Kosovo, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Montenegro, North Macedonia, Romania, Serbia, Palestine, Syria, and Turkey. Its natural habitats are Mediterranean-type shrubby vegetation, sandy shores, arable land, pastureland, plantations, and rural gardens. It is threatened by habitat loss.
Reproduction
Males and females from Greece have a reproductive cycle that begins in April and ends in July. Both sexes achieve sexual maturity when they reach approximately 80 millimeters in body size.
Key Characteristics
• Size: They are exceptionally large for European lizards, growing up to 50 centimeters (20 inches) in total length, with a snout-to-vent length reaching up to 17.4 centimeters.
• Coloring: Mature adults exhibit a striking emerald-green color finely speckled with black. During the breeding season, males develop a distinctive bluish throat and flank.
• Juveniles: Younger lizards look completely different; they are typically brown with three yellowish-white stripes running down their backs. This feature gives them their scientific name trilineata (three-lined).
• Behavior: They are day-active (diurnal) and primarily omnivorous. Like many lizards, they can drop their tails (autotomy) to escape predators.
Habitat & Distribution
The Balkan green lizard is native to Southeastern Europe and parts of the Middle East. Its range spans across countries including Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Montenegro, North Macedonia, Romania, Serbia, Turkey, Syria, and Palestine.
They favor warm environments with dense vegetation, making their homes in Mediterranean-type shrublands, hedgerows, bramble thickets, pastures, and traditional olive groves. Although they are listed as Least Concern by the IUCN, localized populations face continuous pressure from habitat loss.
