It is not a high-fashion model. Woodworthia brunnea is a rugged southern farmer in a moleskin jacket. They are built for a landscape that is often grey, stony, and unforgiving. Growing to a respectable 16 centimetres, they are draped in a sophisticated palette of earthy browns, olives, and greys. Often patterned with V shapes or blotches that allow them to vanish against a piece of schist or a weathered fence post. They are the everyman of the New Zealand lizard world. The gecko you are most likely to spot by torchlight as it scuttles behind a piece of loose bark or a stack of firewood in a Canterbury backyard. The Waitaha Gecko is a biological all-rounder. Unlike sun-worshipping green geckos, the Waitaha is primarily nocturnal. Emerging from its rocky crevice as the sun sets to hunt for moths, flies, and the occasional spider. However, they are not strictly bound by the clock. On a cool southern afternoon, they can often be seen cryptically basking. Exposing just a small portion of their dark bodies to the sun to soak up enough thermal energy to power their night-time excursions. They are incredibly cold-tolerant. Capable of remaining active in temperatures that would send most tropical reptiles into a permanent slumber. This resilience is the secret to their success in the South Island's four seasons in one day climate. Like all native New Zealand geckos, the Waitaha has abandoned the egg-laying strategy of its overseas relatives. They give birth to live young, usually twins, which are born as fully functional, miniature hunters. This internal incubation is a vital survival mechanism in the south, where the ground can freeze solid in winter. The mothers are remarkably long-lived, often reaching 30 to 50 years of age. Which means that the gecko sitting on your garden wall might very well be older than you are. They are also highly social for reptiles. Often found in colonies where dozens of individuals share the same prime real estate. A deep, dry crack in a rock face or a particularly cozy hollow in a mānuka trunk. Protecting the Waitaha Gecko is a challenge of backyard conservation. Because they are so common, it is easy to forget how vulnerable they are. A single roaming cat can decimate a local colony in a few weeks. And the tidying up of old rock-piles and fallen timber often removes the only homes they have left. They are the silent, unblinking residents of our southern suburbs. A link to the ancient, stony heart of New Zealand. To see a Waitaha Gecko's gold-flecked eye reflecting your torchlight is to realise that the wild is not just in the national parks. It is right there, holding onto the wall of your shed, waiting for the next moth to land.
