Like most lacertid lizards of the Mediterranean, the Milos wall lizard is an active, opportunistic forager (8). It feeds mainly on arthropods, such as beetles, ants, insect larvae and spiders. The type of prey taken varies greatly between seasons; for example, in spring, beetles form a major part of the Milos wall lizard’s diet, while ants are favoured in the summer (8) (9).
The Milos wall lizard is active all year round. The breeding season begins in January and continues through to July, although most mating activity occurs in spring. During the breeding season, the male Milos wall lizard is characterised by bright blue-green spots and mating scars (2), probably as a result of territorial fights with other males. The male Milos wall lizard typically maintains a larger territory than the female, and multiple females frequently share the territory of one or more males (10).
Eggs are laid from the middle of March until the end of August, with the female Milos wall lizard producing several small clutches, each containing one to three eggs (1) (2) (3). Eggs laid early in the breeding season typically begin to hatch around mid-April. Juvenile Milos wall lizards are fairly large at hatching, typically measuring between 24 to 31 millimetres (3). Males of this species are known to become sexually mature at around a year old, although most will not reproduce until they are able to establish their own territory in their second year (10).
As in many other lizards, the Milos wall lizard has evolved an effective defence mechanism against predators. If attacked, the Milos wall lizard is able to shed its own tail to facilitate its escape. The tail can continue moving for up to eight minutes after it has been shed, which acts to divert the predator’s attention away from the escaping lizard (11).
