Turkish Gecko

(Click to enlarge)

This is a baby Turkish Gecko, also called the Mediterranean Gecko.
They arrived in America in the mid 1800s on cargo ships, and are fully established across the southern states with seaports. As the years pass, the population is migrating northward, not yet having reached a point where the climate will prove inhospitable.

To those of us who know them well, they are a shy nighttime friend who hangs on the wall near our porch lights eating insects.
The patio light at our house kept burning out it's expensive halogen bulbs, so I hung a shoplight near the glass door and now we can watch a half dozen of them hunting and fighting from our couch every night.

Full-grown specimens run about 3 inches from nose to base of tail.
This one was born a month or two ago, and to get an idea of it's size just remember that it's in the mortar groove between standard bricks.
Even the thumbnail image above is 2 1/2 times actual size.

This is their daytime coloration, although you have to be tricky to get one to come out before sundown. At night they are a pale and ghostly grey/beige color.
You can see through their skin, they don't have eyelids so have to lick their sensors clean, and can climb almost any surface.
