The gecko is a lizard belonging to a large order of reptiles, of which there are nearly 300 species. They are found in the warmer regions of the Earth's surface. Almost all are nocturnal in their habits, and their food is flies, mosquitoes, and other insects. The gecko's construction is such that it is able to ascend a perpendicular wall, and walk inverted on a ceiling. During the day it lies hiding in dark, damp places, and comes forth at evening to get its food. when it utters a short, sharp chirp. In Italy the Gecko is called terrentolo, in Provence tarente, and by the Romans it was called stellio.
