[3][6] Mniarogekko chahoua gets its common name from the moss or lichen-like pattern it displays.

There has been some notation that color could possibly be a geographic indicator in this species as the geckos from the outer islands most often display the lighter gray patterns.

It possesses a strong, well-muscled, fully prehensile tail and is not subject to dropping it as readily as some of its relatives.

Mniarogekko chahoua, like most of the New Caledonian geckos, are seasonally-dependent omnivores and frugivores.

The eggs are generally laid on top of the substrate (usually under loose tree bark and leaf litter) and are guarded by the female.
