Horvath’s rock lizard hibernates from the end of October until April, or earlier if conditions become favourable, with males usually emerging before females. This species is most active early in the morning or in the late afternoon, and takes shelter in the crevices of rocks during the midday hours when the temperature is too high (2).
The breeding season of Horvath’s rock lizard is synchronised to the short Alpine summer, with mating usually taking place from the end of May to the beginning of June. Egg-laying occurs for one week in mid-July, when clutches of three to five eggs are laid in rocky crevices. The eggs hatch at the end of August or beginning of September. The growth of juvenile Horvath’s rock lizards is fast, and sexual maturity is reached after three years (2). This lizard lives for an average of seven to nine years (2).
Horvath’s rock lizard is an opportunistic predator that catches its prey from within rock crevices. It feeds on a variety of prey types depending on the local food availability, although arthropods typically form the main constituent of its diet (2).
The male Horvath’s rock lizard establishes a territory, which it defends from other males (2).
