Native species of southwest Madagascar, this is one of the largest day geckos and is able to reach a length of eleven inches (28cm). Strictly an arboreal species, they have specially adapted feet for climbing. They eat a range of insects, invertebrates and even small lizards but are omnivorous and supplement their diet with soft fruits and nectar. They can be very territorial and the members of the same sex may sometimes fight amongst themselves, which is rare for geckos. They are named after Herbert F. Standing of Madagascar.
