Lizars in Jacó Costa Rica
This gecko is usually found in low elevation areas where humans live, as one might expect, on surfaces such as walls, roofs, or railings.
In Costa Rica the house gecko lives along both coasts up to 1,231 m in elevation. It presumably came to Costa Rica via shipping vessels, as it did to many other parts of the tropics and subtropics. This species lives in regions including southern India, southern China, Malaysia, the Philippines, northern Australia, Guam, the Mediterranean, and Central America.
Hemidactylus frenaus ~~~ House Gecko
BIOLOGY AND NATURAL HISTORY
This common reptile might be seen actively hunting insects during the day, but they are more likely to be seen at night while they stalk insects crowding electric lights. They are fast animals, and have toes constructed to render them capable of running on vertical, smooth surfaces and even upside down.
One of the more talkative reptiles and certainly the most talkative lizard in Costa Rica, the house gecko is sometimes heard before it is seen, with a rapidly repeated chirp or chuck that can be loud and startling when nearby. Both sexes do this, although males do it more, particularly before they attack another male. He will also use the call to attract females.
Females may share nesting sites, but usually pairs of eggs are laid in small nooks near ceilings, beams, or under leaf litter. Females can store sperm in their body for up to 8 months before using it over multiple clutches of eggs while they are isolated from males. This ability is one reason the house gecko has been so effective at colonizing new areas. This species has managed to travel among and survive in many regions of the world. It is believed that the house gecko arrived in Costa Rica as a ship stowaway after 1990. Across most of its range in the world, this gecko is generally found in human-inhabited areas.
