Common House Gecko

It is almost invisible when it is resting on a rock. According to Wikipedia : "The Common House Gecko, scientific name Hemidactylus frenatus, is a native of southeastern Asia. It is also known as the Pacific house gecko, the Asian house gecko, or simply, the house lizard. Most geckos are nocturnal, hiding during the day and foraging for insects at night. They can be seen climbing walls of houses and other buildings in search of insects attracted to porch lights, hence their name "House Gecko". Spread around the world by ships, these geckos are now common in the Deep South of the United States, large parts of tropical and sub-tropical Australia, and many other countries in South and Central America, Africa, Asia, and the Middle East. They grow to a length of between three to six inches (about 7.5–15 cm), and live for about five years. These small geckos are non-venomous and harmless to humans. Medium to large geckos may bite if distressed, however their bite is gentle and will not pierce skin."
