These are Italian Wall Lizards in NY.
No lizards of the family Lacertidae are native to the USA but as a result of the pet trade and deliberate introduction, 3 species now exist here. One, the Western Green Lizard, Lacerta bilineata, is restricted to the Topeka, KS region and is not discussed in this blog. The remaining 2 are both Wall or Ruin Lizards and are in the genus Podarcis. The species are the Italian Wall Lizard, P. siculus and the Common Wall Lizard, P. muralis, both common to abundant species in their European homelands.

Of nomenclatural interest is the fact that rather than subspecies, color and size differences in P. muralis are referred to as morphs, while P. siculus has been broken into so many subspecies that even the researchers can be confused.

Although subspecific/populational size differences can be seen in Europe, both species in the USA are of relatively similar length and overall appearance but generally differ markedly in color.

Both have an adult snout-vent length of about 3 ½” and a tail, if in its original form, of another 3 ½ or 4 inches. They are slender lizards that are of somewhat flattened appearance, especially on cool mornings when they are warming in the sunshine. Fortunately for observers the two do differ markedly in coloration as well as in current range in the USA. Both are habitat generalists, being equally successful in populating residential, agricultural, or dry fields or meadowlands. Both species can climb but the Italian Wall Lizard seems the more apt to use arboreal escape routes.

The Common Wall Lizard, P. muralis, is an overall sand tan and warm brown dorsally and laterally. Originally introduced in Cincinnati this little European lizard is now truly common in that area. It is also now firmly established in northwestern Kentucky.

The Italian Wall Lizard P. siculus differs from the Common Wall Lizard in having a green back and often some green on the sides. It is also at home in both residential and urban areas. It has been reported from CT, MO, KS, NY, CA, NJ, PA, but may now be absent in some regions and present in others.

Meet the Banded Knob-tailed Gecko, N. wheeleri cinctus.
Earlier we discussed the 2 most distinctive Knob-tailed Geckos, the Centralian and the Queensland Rough-skinned species. Today we’ll take a look at two species, the Three-banded and the Banded Knob-tails, respectively known as Nephrurus levis (three subspecies, N.l. levis, N.l. occidentalis and N.l. pibarenis) and N.wheeleri cinctus. As with other members of this genus, these 2 are capable of “barking” vocalizations.

The Three-banded Knob-tailed Gecko, Nephrurus levis, is the most widespread member of this genus on the Australian Continent. Two of the 3 subspecies of this species occur in westernmost Western Australia. The third, has a vast range throughout most of interior Australia. The reference of 3 bands refers to the three narrow light bands, often dark bordered, that cross the dorsum between the back of the head and the shoulders. If taken literally, the reference to smooth in a second common name is erroneous. It is meant only as a comparison to differentiate the relative skin texture of this species from the very roughened dorsal and lateral skin of other members of this genus.

This species has a rather long, somewhat flattened, knob-tipped tail. Counting tail, the length of this species would be about 5 inches. It, like other members of the genus is oviparous.

The more commonly seen of the 2 subspecies of Wheeler’s Knob-tail, is the northernmore form, N. wheeleri cinctus. It has been elevated to full species status, N. cinctus, by some researchers. It is also known as the Banded Knob tail Gecko. It is restricted to Western Australia.

It is a rough-skinned species with the dorsum being much rougher than the sides. Dorsal and lateral coloration is purplish with wide brownish bands.

This species seems to prefer vegetated rocky areas as habitat.

The Banded Knob-tailed Gecko has a rather long, flattened tail tipped with a small knob. Counting the tail, the length of this species would be about 4 ½ inches. It, like other members of the genus is oviparous.

Both the Banded and the Three-banded Knob-tailed Geckos have proven hardy captives and have been bred numerous times by hobbyists. Aridland terrariums are preferred, and several inches of clean sand is a suitable substrate. Watering is a bit of a chore. Besides not recognizing water dishes as moisture sources, their normal activities usually have dishes rapidly sand filled. It has been found that spraying the terrarium sides in the evenings when these lizards are active is the best solution to the watering question.
