A research about the plant use of the red-eyed tree frog (agalychnis callidryas) during the mating season is being conducted by the Applied Biology student from HAS University (Netherlands), Lars Vane.

During the 20 weeks that the study will last, the student basically search for the frogs at night with a flashlight and he takes note on which plant they are, then he tries to catch the animal and try to see if it is a male or a female. Then he measures the total length and the legs of the frogs to see if there is a difference between males and females.

The red-eyed tree frog mostly prefer plants with big leaves, such as palms, banana plants and the guacimo blanco, but this can change after the study is finished and he can analyze the results.

At this point, after 10 weeks, he has found 172 frogs and clutches of eggs. On his opinion males are way easier to spots than females: so far he counted around 140 males, but just 17 females.

Other important information is that he also detected some predators for the eggs of the red-eyed tree frog, like the cat-eyed snake and the big crickets.

For the final results of this study, we will have to wait for other 10 weeks, and keep learning more interesting facts about the red-eyed tree frog.
