Podarcis erhardii, also referred to as the Aegean wall lizard or Erhard’s wall lizard is one of the lizard species from the family Lacertidae.
This lizard is a native of the southwestern region of Europe. The name erhardii is derived from a certain German naturalist called Dr. Erhard. He was the author of “Fauna See Cycladen.”
Lizards are found in the Balkan peninsula and the Aegean islands.
Podarcis erhardii can be found in the mainlands of Albania, North Macedonia, and South Bulgaria.
Its geographic range also extends to the northeastern part of the peninsula of Penelope in Greece.
They are usually preyed on by birds, so they survive and avoid attacks by using camouflage.
This lizard settles for backgrounds that align with their skin color to shield themselves from the sight of their predators.

Description and Size
The Podarcis erhardii has a body length of 7 centimeters, which is 2.8 inches. This miniature creature has a tail that’s twice its body length. It also has smooth skin with a broad head. This lizard has varying skin coloring and patterns.
The major coloring and pattern of the males are usually grey or brown, sometimes green. Females’ skins are usually striped.
Two dark and spotty lines border the two white stripes on their backs. A dark line is also in the middle of the lizard’s back.
The males have a net-like skin pattern. Their bellies and, most times, their throats are usually white, orange, yellow, or red.
For the ones in the Aegean islands, those body areas are typically green, blue, or grey. While they don’t have spotted bellies, there are generally blue spots on their hind legs.
The Erhard’s wall lizards from the eastern region of the Aegean islands are considerably different from those on the central Cyclades.
They have reduced greyish or brownish skin coloration. They are also short-limbed and have pointy snouts. They established populations on numerous tiny islets that hadn’t been habited before.
They are set apart from the central Cyclades by waters reaching several hundred meters. They are more terrestrial than their counterparts on the Cyclades.
They cannot be confused with other lizard species because they are the only Lacertids in their territory.
Habitat
The Podarcis erhardii’s primary habitat usually includes dry or rocky locations. It also includes low and dense bushes. They also live in open areas such as plant-covered dunes.
Diet
Their primary diet consists of arthropods, insects such as ants, crickets, and many more.

The Podarcis erhardii’s mating season usually occurs during spring. They usually lay their eggs at the beginning of summer, which are later hatched in September. The lizard’s offspring has a body length measurement of 3 centimeters.
Subspecies
Up to 28 subspecies of Podarcis erhardii have been qualified as valid.
Nonetheless, only four have been identified, and they include:
- Podarcis erhardii livadiacus
- Podarcis erhardii rivet
- Podarcis erhardii thessalicus
- Podarcis erhardii ruthvenii
Conservation Status
