House lizards are common inhabitants of many homes, especially in warmer climates. These small reptiles, often seen scurrying across walls and ceilings, do indeed lay eggs. Understanding their egg-laying behavior provides insight into their life cycle. This article explores house lizard reproduction, the appearance of their eggs, typical nesting locations, and the journey from egg to hatchling.
Understanding House Lizard Reproduction
House lizards, primarily common house geckos, are oviparous, meaning they reproduce by laying eggs. Female house geckos typically lay hard-shelled eggs, usually two at a time per clutch. These females can lay multiple clutches, sometimes two to three batches, within a single mating season.
Reproductive activity for house geckos can occur year-round in subtropical areas, though it might decrease in cooler months. After mating, a female house lizard will generally lay her eggs within two to four weeks. House lizards do not exhibit parental care after the eggs are laid, leaving them to develop independently. The female seeks out suitable locations to deposit her eggs, focusing on protection and environmental stability for the developing embryos.
What House Lizard Eggs Look Like
House lizard eggs are generally small, often compared to the size of a pea or a fingernail. They are typically oval-shaped and usually white or off-white in color. When freshly laid, the eggs are somewhat soft but quickly harden, becoming firm to the touch.
The texture of house lizard eggs is often described as leathery or slightly calcified, distinguishing them from brittle bird eggs. This texture provides some flexibility and allows them to adapt to uneven surfaces where they might be laid. As they near hatching time, a network of pinkish veins might become visible on the egg’s surface. These characteristics help in identifying house lizard eggs.
Common Egg-Laying Spots
House lizards are particular about where they deposit their eggs, prioritizing warmth, seclusion, and protection from potential disturbances. They often choose hidden and undisturbed locations within a home. Common indoor egg-laying spots include cracks in walls, behind furniture, and inside crevices.
They also favor areas like under loose wallpaper, in cluttered spaces, or within rarely disturbed containers. Moist and dark environments, such as basements or cabinets under sinks, are particularly attractive for egg deposition. Other potential sites include behind bookshelves, in piles of newspapers, or even in the soil of indoor potted plants. Lizards select these spots to ensure the eggs are camouflaged and insulated, increasing the chances of successful development.
From Egg to Hatchling
The incubation period for house lizard eggs typically ranges from 40 to 60 days. This duration can vary based on factors such as the specific species of house lizard and the ambient temperature and humidity of the environment. Warmer temperatures generally lead to a faster development process.
During incubation, the embryo develops inside the egg, drawing nourishment from the yolk. As hatching approaches, the egg may sometimes “sweat” or produce small droplets of water on its outer shell. Once ready, the hatchling emerges, typically as a miniature version of an adult house lizard. These newly hatched lizards are immediately independent and capable of fending for themselves, needing no parental care.
