Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Australia, Brazil, Costa Rica, Indonesia, and Mexico. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Birdwing

The common birdwing (<em>Troides helena</em>) is a large and striking butterfly of the family Papilionidae, classified as Least Concern on the IUCN Red List. It inhabits terrestrial and freshwater environments across its range in South and Southeast Asia. <em>Troides helena</em> is among the larger birdwing butterflies, with males displaying vivid yellow and black coloration on the hindwings, while females are typically larger and more cryptically marked. The species is often found in tropical and subtropical forest habitats, where it visits flowering plants for nectar. Larvae of birdwing butterflies typically feed on Aristolochia vines, which contain toxic alkaloids that are sequestered by the caterpillars and retained in adult tissues as a chemical defense. Despite its Least Concern status, birdwing butterflies are subject to trade regulations due to their attractiveness to collectors. Biological traits of this species remain poorly documented in the scientific literature.

Green Sea Turtle

La tortuga verde (Chelonia mydas) es una de las tortugas marinas más grandes. Su nombre proviene del color verde de su cartílago y grasa, no del caparazón.
