These are the white spots which give this species its name.
Male/Female Differences

The spots are sometimes not easily visible on juveniles.
Similar Non-native Geckos Found in California
Moorish Geckos have more wrinkled and tubercular skin and do not have white spots on the shoulders.
Mediterranean Geckos are smaller with fewer large tubercles and lack the white spots on the shoulders.
Peninsular Leaf-toed Geckos are smaller, with fewer tubercles and no white spots and are found on rocks in the Colorado Desert in the extreme south-central part of the state.

Behavior and Life History
Pugnacious, biting readily when grabbed.
Makes an audible squeaking sound when threatened or disputing territory with others of the species.
Diet and Feeding
Prey includes invertebrates and small lizards.
In northern Africa, females produce several sets of 2 eggs each season.

In California, found on urban buildings and in urban alleys.

Geographical Range
Native to parts of northern Africa.

Range in California

A population of T. annularis has been documented in Redlands, San Bernardino County.

In 2006 it was reported on the internet that there was a population of these geckos in Redlands. Comments in the H.E.R.P. database records indicate they have been present at least as early as 2002.

An unconfirmed rumor claims that the site of introduction was a pet store that was in the area but which no longer exists, that the store purchased a large group of the geckos in 1995, that an employee accidentally left their cage doors open and a number of geckos escaped into the store, and that despite store employees efforts to collect them all, they began breeding and about a year later had become established outside the store, which was confirmed when neighbors began bringing juveniles to the store to find out what they were.

William Flaxington confirmed that the geckos were still there in 2007. Some of his photos can be seen above.
Jonathan Hakkim confirmed that they were still present in 2010 and 2012.
You should be able to see Jonathan's photos and those taken by other photographers and their habitat on the H.E.R.P. dababase here.  If this link no longer works, go to the H.E.R.P. database and search for Tarentola annularis.

In 2013 I gave Kent Beaman of the Natural History Museum of Los Angeles the locality information William Flaxington gave me for the geckos. Beaman had already searched for the geckos in Redlands but in the wrong area. With the correct location information he was able to collect some specimens for the museum and publish the first documentation that the species was established in California in September, 2014. (Kent R. Beaman and David M. Goodward. Verified by Clark Mahrdt. Herpetological Review 45(3), 2014). (Their note neglected to mention William Flaxington's contribution to the effort.)

The species Tarentola annularis - Ringed Wall Gecko, is listed on the 2008 SSAR Alien Species list as native to northern Africa and established in Florida in Lee and Miami-Dade counties - possibly established from a pet store release in Tallahassee.
