The dorsal body colour is a brilliant green with a diffuse blue area on the neck region.

There are irregular shaped orange-red bars and spots on the back and tail, the tip of which may be blue.

The Mauritius lowland forest day gecko prefers large trees such as palms and acacia species.

Much of the lowland forest of Mauritius, which is the original habitat of P. guimbeaui, has been cleared to make way for sugar cane plantations.

The Mauritius lowland forest day gecko is rather shy as it is heavily predated by different bird species.

The Mauritius lowland forest day gecko is an egg gluer and often a colony nester.

In captivity, P. guimbeaui can be fed with crickets, commercial fructivorous gecko diets, wax moths, fruits flies, mealworms, and houseflies.
