Tropical House Gecko

The tropical house gecko (Hemidactylus mabouia) is a small, nocturnal gecko commonly found in urban and rural areas across tropical and subtropical regions of Africa. It is characterized by its light brown to grayish skin, covered in darker spots and patches, which provide excellent camouflage against tree bark and buildings. Adult geckos typically measure between 7.5 to 15 cm (3-6 in) in length. It has large, lidless eyes with vertical pupils, adapted for night vision. This species is known for its vocalizations, particularly a soft chirping sound. 

Like many other lizards, these geckos can detach their tail when threatened, a defense mechanism known as autotomy. The tail continues to wriggle, distracting the predator while the gecko escapes.

Tropical house geckos thrive in a variety of habitats but are most commonly found in human dwellings, living on walls and ceilings. They are adaptable creatures and can also be found in forests, savannas, and grasslands. These geckos are insectivorous, feeding primarily on mosquitoes, moths, and other small insects. They are skilled hunters, using their stealth and quick movements to catch prey, and their sticky toe pads (with millions of tiny hairs) enable them to move easily across vertical surfaces and ceilings.

The breeding season for the tropical house gecko varies by region but typically occurs during the warmer and wetter months. Females lay a small clutch of eggs, usually two, which are often attached to walls or hidden in crevices. The eggs are oval and have a hard, calcified shell. Incubation can last from 40 to 60 days, depending on temperature and humidity. Hatchlings are independent from birth, possessing the same climbing abilities and diet as adults.

The tropical house gecko has been introduced to various parts of the world, including large portions of South America, the Caribbean, and Florida in the United Sates. These introductions are thought to have occurred through shipping and trade activities. In new environments, they quickly adapt and can sometimes outcompete native gecko species.

The tropical house gecko is not considered threatened, mainly due to its adaptability and success in urban environments. However, in areas where it is an introduced species, it may impact native gecko populations. It is listed as least concern on the IUCN Red List.
