The male Mediterranean tree frog calls from trees as well as from water and land, producing a loud, deep ‘cra-a-ar’ (2). The resonant calls can be heard some distance away, particularly when calling activity peaks during the breeding season, and many males calling together may produce a deafening chorus (2) (3). The timing of breeding varies with location, but is usually between March and April in North Africa, from April to June in France, from December to January in Portugal, and from about March in the Basque Country, Spain (2) (3) (7).
The Mediterranean tree frog lays between 800 and 1,000 eggs, in clumps of around 10 to 30. The female usually attaches the eggs to aquatic vegetation near the shore, where they are fertilised by the male, and the frogs leave the water after breeding, moving away into nearby trees (2) (3). The eggs of this species are yellowish and hatch after eight to ten days. The tadpoles measure just 5 to 8 millimetres on hatching, and grow to a total length of about 55 millimetres, with metamorphosis occurring around three to four months after the tadpoles hatch (2) (3).
The diet of the Mediterranean tree frog consists of a variety of invertebrates, including beetles, butterflies, moths, flies, ants and spiders (2) (3). This species may be active by both day and night (3), but it may hibernate during the winter months in some areas (7), while in others it becomes inactive (aestivates) in the summer (3).
