The
European green lizard (
Lacerta viridis) is a large
lizard distributed across European midlatitudes from
Slovenia and eastern
Austria to as far east as the
Black Sea coasts of
Ukraine and
Turkey. It is often seen sunning on rocks or lawns, or sheltering amongst bushes.
Taxonomy
There is an ongoing discussion as to whether
Lacerta viridis and
Lacerta bilineata are separate species. Genetic data weakly supports their separation into two species but more investigation needs to be done.

Description
The lizard reaches up to 15 cm (5.9 in) from the tip of the muzzle to the
cloaca.
The tail can be up to twice the length of the body, total length is up
to 40 cm (16 in). This lizard sometimes sheds its tail (
autotomy) to evade the grasp of a predator, regrowing it later.
The male has a larger head and a uniform green coloring punctuated
with small spots that are more pronounced upon its back. The throat is
bluish in the adult male and to a lesser extent in the female. The
female is more slender than the male and has a more uniform coloration,
often displaying between two and four light bands bordered by black
spots.
Distribution and habitat
The
European green lizard is native to southeastern Europe. Its range
extends from southern Germany, Austria, eastern Italy, Croatia, Bosnia
& Herzegovina, Serbia, Montenegro and Greece to southern Ukraine,
Romania, Bulgaria and western Turkey. It has been introduced into the
state of Kansas in the United States.

It is known from elevations up to 2,200 m (7,218 ft) above sea level
and its typical habitat is dense bushy vegetation in open woodland,
hedgerows, field margins, embankments and bramble thickets. In the
northern part of its range it may be found on bushy heathland and in the
southern part it prefers damp locations.

Behavior
The
European green lizard lives on the ground and in low, dense vegetation
and likes to bask in the sun, early and late in the day. It feeds mainly
on
insects and other small invertebrates but it also sometimes takes fruit, birds eggs, fledglings, small lizards and even
mice.
In spring, the female lays six to twenty eggs which hatch in two to
four months. Newly hatched juveniles are pale brown with a snout-to-vent
length of 3 to 4 cm (1.2 to 1.6 in). They become mature the following
year by which time they will have doubled in size.
[2]
Status
The
IUCN lists the European green lizard as being of "
Least Concern".
This is because it has a wide range and is common in at least part of
that range. It is an adaptable species and no substantial threats have
been identified over most of its range. However, in Turkey it may be
impacted by the use of pesticides.
