Brookesia betschi
Brookesia betschi, also known as Blanc's leaf chameleon or the Marojejy leaf chameleon, is a small lizard species endemic to the forests of northern Madagascar. This diurnal reptile relies on its cryptic coloration for camouflage and inhabits subhumid forests at high altitudes. It is oviparous and faces threats from habitat destruction.

About Brookesia betschi
Brookesia betschi, commonly recognized as Blanc's leaf chameleon or the Marojejy leaf chameleon, is a species of lizard belonging to the Chamaeleonidae family. This species is exclusively found in the island nation of Madagascar.
Taxonomy and Discovery
The species was first formally described by Édouard-Raoul Brygoo, Charles Pierre Blanc, and Charles Antoine Domergue in 1974. The original specimen was collected in 1973 from a forest in Marojejy at an elevation of 1,300 meters. The specific epithet, "betschi," was chosen to honor the French biologist Jean-Marie Betsch.
Geographic Range and Habitat
Brookesia betschi inhabits the forests of northern Madagascar. Its range extends across subhumid forest environments within several reserves, including Manongarivo Reserve, Anjanaharibe-Sud Reserve, Marojejy National Park, and Tsaratanana Reserve. These chameleons are found at altitudes typically between 1,150 and 1,650 meters. The total area it occupies is approximately 11,090 square kilometers.
Behavior and Diet
This chameleon is diurnal, meaning it is active during daylight hours. Its days are spent foraging through leaf litter in search of insects and other small invertebrates. When faced with a perceived threat, Brookesia betschi employs a defense mechanism of remaining motionless, relying on its natural cryptic coloration for camouflage against its surroundings. At night, it perches on low-lying trees and plants, a behavior that makes it more conspicuous.
Reproduction
Brookesia betschi reproduces by laying eggs, classifying it as oviparous.
Conservation Status
The International Union for Conservation of Nature (IUCN) has classified the Marojejy leaf chameleon as Near Threatened. This status is attributed to the significant loss of rainforest habitat in northern Madagascar. The species possesses highly specialized microhabitat requirements and is intolerant of environmental disturbances. Its survival is threatened by forest destruction for agricultural purposes, particularly through slash-and-burn techniques, and by logging activities. While its habitat is fragmented, each section is believed to be large enough to sustain a viable population.
