Then, after three months, tadpoles metamorphose into frogs. Individual eggs are about 1.5 mm in diameter. About 800 to 1000 eggs are laid in clumps the size of a walnut. After a spring rain, the males will call females from low vegetation or shallow ponds. Males will often change breeding ponds, even within the same breeding season. They croak in the breeding season, even when migrating to their mating pools or ponds. Reproduction Male chorus Calling males at nightĮuropean tree frogs reproduce in stagnant bodies of water, such as lakes, ponds, swamps, reservoirs, and sometimes puddles, from late March to June.
DO PET TREE FROGS HIBERNATE SKIN
Depending on subspecies, temperature, humidity, and the frog's 'mood', skin colour ranges from bright to olive green, grey, brown and yellow.Historically, tree frogs were used as barometers because they respond to approaching rain by croaking.They tend to avoid dark or thick forests, and they are able to tolerate some periods of dryness therefore, sometimes they are found in dry habitats. Įuropean tree frogs can be found in marshlands, damp meadows, reed beds, parks, gardens, vineyards, orchards, stream banks, lakeshores, or humid or dry forests. It has also been introduced to the United Kingdom, (although at least one British population, now thought to be extinct, may have been native ), and it has been reintroduced to Latvia. This species complex is native to these countries:Īlbania Armenia Austria Azerbaijan Belarus Belgium Bosnia and Herzegovina Bulgaria Croatia Cyprus the Czech Republic Denmark France Georgia Germany Greece Hungary Israel (found in the Ayalon Valley) Italy Liechtenstein Lithuania Luxembourg Macedonia, the Republic of Moldova Montenegro the Netherlands Poland Portugal Romania the Russian Federation Serbia Slovakia Slovenia Sweden Switzerland Turkey Ukraine. and are found across most of Europe (except Ireland), northwest Africa, and temperate Asia to Japan. arborea species complex are the only representatives of the widespread tree frog family (Hylidae) indigenous to mainland Europe. Like other frogs, their hind legs are much larger and stronger than the fore legs, enabling the frogs to jump rapidly. The discs on the frog's toes, which it uses to climb trees and hedges, is a characteristic feature of H. arborea is rounded, the lip drops strongly, the pupil has the shape of a horizontal ellipse, and the tympanum is clearly recognizable. Females have white throats, while males have golden brown throats with large (folded) vocal sacs. Their ventral skin is a whitish color, and the dorsal and ventral skin is separated by a dark brown lateral stripe from the eyes to the groin. Their dorsal skin can be green, gray, or tan depending on the temperature, humidity, or their mood.
Their dorsal skin is smooth, while their ventral skin is granular. Description Įuropean tree frogs are small males range from 32–43 mm (1.3–1.7 in) in length, and females range from 40–50 mm (1.6–2.0 in) in length. orientalis of parts of Eastern Europe, Turkey and the Black Sea and Caspian Sea regions), limiting the true European tree frog to Europe from France to Poland and Greece. meridionalis of parts of southwestern Europe and northern Africa, and H.
As traditionally defined, it was found throughout much of Europe, Asia and northern Africa, but based on molecular genetic and other data several populations formerly included in it are now recognized as separate species (for example, H.
The European tree frog ( Hyla arborea) is a small tree frog. Some populations (Iberian Peninsula, parts of Eastern Europe, Turkey, and the Black Sea and Caspian Sea regions) are now recognized as separate species
