### Identification The Mediterranean House Gecko is a small, ghostly reptile, typically reaching 4–5 inches in length. Its most striking feature is its "bumpy" skin, covered in prominent, light-colored tubercles (warts) that give it a textured appearance. Their coloration is highly variable—ranging from a mottled sandy-brown to a pale, translucent pink—allowing them to nearly disappear against stone or stucco. Look for their vertical pupils and lack of eyelids; they have a fixed, wide-eyed stare and must lick their eyes to keep them moist. Their toes are distinctively widened into adhesive pads, though unlike some relatives, they possess small claws emerging from the pads.
### Habitat & Range Originally native to the Mediterranean Basin and Western Asia, this resilient "hitchhiker" has spread globally via human commerce. They are now common across the southern United States and Mexico. You won’t find them in deep forests; they prefer "vertical deserts." In their native range, they haunt rocky cliffs and caves, but in urban settings, they thrive on backyard fences, brick walls, and behind shutters—anywhere with deep crevices to hide during the day.
### Behaviour Strictly nocturnal, these geckos emerge at dusk. They are surprisingly social and vocal; a patient observer might hear a series of faint, bird-like *chirps* or clicks used to establish territory or attract mates. They are masters of the "sit-and-wait" ambush, remaining motionless for hours. If cornered, they utilize caudal autotomy—dropping their tail, which continues to thrash violently to distract a predator while the gecko slips away to regrow a new one.
### Diet These are opportunistic insectivores. They view an illuminated porch light as a high-calorie buffet, congregating nearby to snatch up moths, crickets, beetles, and spiders. Their hunting is surgical: a slow, calculated stalk followed by a lightning-fast lunging snap.
### Fascinating Fact The Mediterranean House Gecko is a master of molecular physics! Their toe pads are covered in millions of microscopic hairs called *setae*. These hairs are so fine they engage with the molecules of a surface using Van der Waals forces, allowing the gecko to sprint across a polished glass ceiling without a drop of glue or suction.
