Hyla arborea

These popular anuran amphibians are small frogs with very interesting characteristics. They are excellent climbers, often living in trees but can also climb on flat surfaces. To hide from predators they adjust their body colors just like chameleons. However, when camouflage does not work the venom produced by the skin glands comes into play, which can save the life of this small animal.

Because of their interesting coloration, three frogs are eagerly kept in terrariums.

European tree frog
The European tree frog is an amphibian belonging to the riverine family.

The riverine family includes about 800 species of animals divided into 48 genera.

It is found in Europe and Asia Minor.

Its range includes most of the Iberian Peninsula, and central Europe except Italy, Ukraine, the Balkans, Crete, northwestern Turkey, Georgia, Azerbaijan, and the southern coast of the Caspian Sea.

It is a lowland species, sometimes found in areas up to 1500 meters above sea level.

It lives in clear-cut deciduous forests, shrubby areas, lush meadows, and coastal thickets. Ruffles shy away from dark and heavily vegetated forests.

They are small amphibians, with females being slightly larger than males.

Their bodies are slender and equipped with long legs, enabling rapid and long leaps. A typical male reaches 3.2 to 4.3 cm in body length and females 4 to 5 cm. The weight of males is 8 to 9 g and females 11 even up to 15 g in extreme cases.

The skin of European tree frogs is smooth on the back and porous on the abdomen.

Their back can be green, gray, or light brown. The color can change due to temperature, humidity, or mood. The belly is whitish and is separated from the dorsal color by a thin dark line running from the snout and eye to the pelvis. The throat is white in females and golden brown in males.

Males are equipped with a large and variably colored resonance sac.

It is used during the mating season to attract females. The more colorful it is, the better it indicates the condition of its bearer.

They are carnivorous.

They hunt mainly arthropods. Their prey is usually spiders, flies, beetles, butterflies, and caterpillars. They catch many of their prey in flight, so flying insects make up most of their diet. They hunt from concealment, remaining motionless and waiting for a good opportunity to instantly snatch their prey with their agile tongue.

The mating season begins in May or even late April and lasts until late July.

Males then gather on the banks of bodies of water or directly on their surface and begin their trailing call, which begins to sound in the evening and lasts until late at night. The district of a single male tree frog is three meters. Amphibians try to keep inside them and chase away intruders. Females choose mates based on their voice and the coloration of the resonance sac and the ribbon passing through the side of the body.

Females lay 800 to 1000 eggs grouped in walnut-sized clusters in the water.

The eggs are 1.5 mm in diameter. After 10 to 14 days, tadpoles hatch from them. The earlier the eggs are laid, the larger and more adult the tadpoles will grow.

About three months after hatching, the tadpoles transform.

This usually takes place between late July and early August.

The lifespan of a European tree frog is about 15 years.

This is probably their maximum lifespan; in the wild, they usually reach a maximum age of 6 years.

Although European tree frogs can migrate, they often return to the pond where they are already living.

They are also reluctant to settle in a new pond if it is more than 750 meters away from others, and is not overgrown by bushes and tall greenery. They also prefer neutral or slightly alkaline waters.

They are excellent climbers.

They can climb even on vertical smooth surfaces and have been found as high as 10 meters.

They can change their skin color, often doing so to adapt to their surroundings.

It takes these amphibians about 20 minutes to change color from light green to almost dark.

Tree frogs traipse around in a tree.

This distinguishes them from frogs, which croak or retch. The jabber has a different sound, similar to that of a rattle. You can listen to it on the National Forest website.

The European tree frog is under strict species protection in Poland.

The International Union for Conservation of Nature has revised the species’ endangered status several times in recent years. In 2004 it was even considered near threatened (NT) but is now classified as a species of least concern (LC).
