We studied the food habits of the Italian wall lizard, Podarcis sicula, that was introduced to Long Island, New York in 1966. We recovered 436 prey items from 96 lizards. There was no significant relationship between the percentage of lizards without prey items and date of capture. On average, females had significantly more prey items per lizard, lower overall prey diversity and lower prey evenness, than did males. This suggests important differences in foraging habits between the sexes. We found remarkably high similarity between prey species diversity for the Long Island and two of four European populations. There was no correlation between prey size and either head width or snout-vent length of the lizards.
