Common House Gecko

Some other names for this species:

Asian House Gecko, Spiny-tailed House Gecko, Chichak

Puri Kamandalu, Ubud, Bali, Indonesia
Common House Gecko (Hemidactylus frenatus)
Common House Gecko (Hemidactylus frenatus)
These little geckos abound in Bali and throughout southeast Asia. They're called "Chichak" locally for the sound of their calls. They would sometimes wake us up at night by calling right above our bed. Their color is quite variable, changing based on temperature and background. These two were both on stone gates at Puri Kamandalu at night.

Common House Gecko (Hemidactylus frenatus)
Like most geckos, they're mostly nocturnal, but they're also often seen during overcast days. This one was hanging out on a hotel wall during the day. Its tail has been regenerated and the second-generation one isn't spiny.
Puri Santrian, Sanur, Bali, Indonesia
Common House Gecko (Hemidactylus frenatus)
Common House Gecko (Hemidactylus frenatus)
Here are a couple more from a different part of Bali. The one on the tree is showing off some impressive camouflage. Its tail is curled around but is difficult to distinguish from the branch.
Chez Robert grounds, Antsiranana province, Madagascar
Common House Gecko (Hemidactylus frenatus)

This is one of the two cosmopolitan species of Hemidactylus geckos found in Madagascar along with much of the rest of the tropical world. The other is Hemidactylus mabouia, which we had seen earlier in Maroantsetra.

This gecko had regenerated its tail, and had a number of red mites around its back legs, but otherwise seemed fat and happy.

Here is a list of all the reptiles and frogs I saw on this trip to Madagascar.

Anjajavy, Mahajanga province, Madagascar
Common House Gecko (Hemidactylus frenatus)
I was setting up my camera to photograph this gecko at the base of a palm tree when a woman with a drink in her hand came stumbling my way trying to see what I was aiming at. She leaned way over between my tripod and the palm tree to get a good look, which of course scared the little gecko away, and I got no more photos. Oh well, not the most exciting species anyway.
Anjajavy, Mahajanga province, Madagascar
Common House Gecko (Hemidactylus frenatus)
I found this small gecko sleeping in the broad leaves of a small palm along the edge of Anjajavy's garden pond.
East Point Nature Reserve, Darwin, Northern Territory, Australia
Common House Gecko (Hemidactylus frenatus)

Australia has many fine gecko species, such as this one and this one and this one. You might think that a continent with so many fine geckos would not need this drab cosmopolitan invasive gecko. But you would be wrong..

I’ve written up an account of this three-week trip to Australia here.

Gagudju Crocodile Lodge, Jabiru, Kakadu National Park, Northern Territory, Australia
Common House Gecko (Hemidactylus frenatus)

Most of the Hemidactylus frenatus that have become established in Australia hang out on buildings. Here’s one on the side of a wonderfully crocodile-shaped Holiday Inn.

Gagudju Lodge Cooinda, Kakadu National Park, Northern Territory, Australia
Common House Gecko (Hemidactylus frenatus)

A few days later, I had begun to lose all interest in these omnipresent non-native drab geckos. When this one put in an appearance at the outdoor dining area of the Cooinda lodge, I couldn’t be bothered to get out my real camera, so I took a macro shot from an inch or two away with a little bitty camera, resulting in that oh-so-desirable fish eye effect.

Evergreen Lodge grounds, Limon province, Costa Rica
Common House Gecko (Hemidactylus frenatus)
I believe this is the least interesting herp in Costa Rica. However, it's a little bit fun to see it in more and more countries. And little baby ones are cute.
