Yellow-headed Day Gecko

Phelsuma klemmeri

Also known as Neon Day Gecko, Cheerful Day Gecko, Klemmer's Day Gecko

Yellow-headed day geckos are slender, remarkably agile climbers that spend their days basking and foraging along smooth bamboo stems in northwest Madagascar. Their flattened bodies allow them to slip into narrow cracks and hollow cane nodes at the first sign of movement. Unlike most nocturnal geckos, they possess round pupils adapted for brilliant daylight vision, navigating their vertical microhabitat with exceptional speed and spatial awareness.

Support conservation
Never disturb bamboo canes or capture wild individuals; observe from several meters away to prevent stress.
Responsible observation
  • Spotting Location: Scan mature bamboo stalks in sunlit clearings where individuals bask in early morning.
  • Approach Distance: Move slowly and avoid sudden shadows, as these skittish lizards dart into hollow stems instantly.
