call. While conspicuous vocalization helps male H. fleischmanni attract female individuals, it also increases their risk of exposure to predators. The glass frog's reproduction cycle begins during the rainy season. From May to September, which is the breeding season of the H. fleischmanii frogs, females H. fleischmanni will constantly appear for mating. Female H. fleischmannis stop moving around vegetation close to calling male frogs. The female will then gently push on the male from the side and crawl under them, after that the male frog will clasp the female frog. That is the process of amplexus. Female H. fleischmanni prefer to lay their eggs on overhanging leaves by the river. The number of eggs is dependent on the time of year they are laid. Due to the large number of its natural predators, roughly 80% of the clutches are eaten and/or destroyed. For instance, some risks the eggs face are infections by fungus, or being eaten by larger predators such as crickets and possums. The hatched tadpoles will fall into the river and stay in the silt at the bottom of the river. The male frog takes precautions to keep his eggs safe, such as remaining at the clutch to guard them, or urinating on the eggs to ensure that they do not dry out. The eggs hatch after approximately 10–15 days. The tadpoles that fall into the water usually remain hidden in debris at the bottom of the stream. Their growth is time-consuming, and it takes between 1–2 years for the tadpoles to fully mature. Full gestation time, from egg laying to hatching, spans approximately 8 to 21 days. All the tadpoles in the clutch hatch within a day, but the tadpoles disappear within 2–3 days. The development of tadpoles will show a series of color changes. They go from yellow to orange to red, and hatching occurs almost exclusively in the orange or red stage. The yellow tadpoles may not be able to survive on their own, so the disappearance of the yellow tadpoles is most likely due to predators. However, when the tadpoles reached the orange stage on the eighth and ninth days, they will have enough ability to survive on their own. Mating Female H. fleischmanni lay and deposit eggs close to the calling site so they can be defended by males. Male attend to eggs by returning to the same calling site in succession and
