Lampropeltis zonata, also known as the eastern garter snake, is a species of snake that's quite fascinating.
They have a slender build, typically growing up to 2-3 feet in length, with a brown or grayish-brown coloration.
Their scales are smooth and shiny, which helps them move quickly and easily through their habitats.
The eastern garter snake's distribution spans across the eastern and central regions of North America, from Canada to Mexico.
Physical Characteristics
Lampropeltis zonata can reach a total body length of up to 122.5 cm, although most are shorter than 100 cm long. The scales are smooth and unkeeled, with 21 to 23 dorsal body scale rows at mid-body.
The venter has 194 to 227 ventrals, 45 to 62 subcaudals, and an undivided anal plate. Each maxilla on this snake has 11 to 13 teeth.
Males have 45 to 62 subcaudals and tail lengths that average 18.2% of total body length, while females have 46 to 56 subcaudals and tail lengths averaging 17.5% of total body length.
The slender, cylindrical body of this snake is patterned with black, white (or occasionally yellow), and red bands, with the red bands always bordered by black bands on both sides. The black and red bands generally extend onto the white venter, which may be speckled with black marks posteriorly.
There are seven described subspecies, of which five occur north of Mexico.
Here are some key physical characteristics of Lampropeltis zonata:
- Range: 51 to 122.5 cm (20.08 to 48.23 in)
- Average length: less than 100 cm
These snakes generally reach maturity at a SVL (snout to vent length) of roughly 45 centimeters. In terms of total body length, however, males reach maturity at 50.7 centimeters, and females reach maturity at 54.7 centimeters.

Lockington, 1835
Lockington, 1835 was a pivotal year for the discovery of a new species.
The Lockington's Spiny Babbler was first described by John Gould, an Australian ornithologist.
This species was found in the tropical forests of New Guinea.
It's a relatively small bird, measuring around 15 centimeters in length.
Habitat and Distribution
Lampropeltis zonata is a habitat generalist, meaning it can be found in a wide variety of habitats. These include moist woodlands such as coniferous forests, oak woodlands, chaparral, or coastal sage scrub.
In these areas, it's commonly located within riparian zones with ample rocks and rotting logs where the sun reaches. This type of habitat provides the perfect conditions for the snakes to thrive.
The snakes inhabit elevations ranging from sea level to 3,000 m above sea level, which is quite impressive considering the diversity of habitats they can be found in.
Here are some of the specific habitats where Lampropeltis zonata can be found:
- Habitat Regions: temperate, terrestrial
- Terrestrial Biomes: forest, scrub forest
- Range elevation: sea level to 3000 m (or 9842.52 ft)
- Other Physical Features: heterothermic
Habitat
Lampropeltis zonata is a habitat generalist, found in a wide variety of habitats, including moist woodlands, coniferous forests, and coastal sage scrub.
Most often, it's associated with riparian zones, where the sun reaches, and on south-facing, rocky slopes of stream canyons. These areas provide the perfect conditions for the snakes to thrive.
The snakes inhabit elevations ranging from sea level to 3,000 meters above sea level, which is quite a wide range. They can be found in terrestrial biomes such as forests and scrub forests.
Here are the different habitats where Lampropeltis zonata can be found:
- temperate
- terrestrial
The snakes can also be found in riparian woodlands, usually in canyon bottoms, that have western sycamore, Fremont's cottonwood, coast live oak, willows, wild rose, and blackberries.
Description and Range
The California mountain kingsnake is a medium-sized snake, typically ranging from 1.5 to 3 feet in length.
Its physical description is quite distinctive, featuring red, black, and white bands that are bordered by black on the red bands.
No other snake in Washington has this unique color pattern, making it relatively easy to identify.
This species superficially resembles the venomous coral snake, but it's completely harmless.
Life Cycle and Behavior
Lampropeltis zonata is a secretive snake that's mostly active from late March to early November in California, although it may emerge on warm, sunny days during mild winters.
It's a good climber, often found coiled in decaying cavities of oak trees over 1.5 meters above ground.
This snake generally spends most of its time underground, under surface objects, or inside rock crevices, making it difficult to spot.
Here are some key behaviors associated with Lampropeltis zonata:
- terricolous
- diurnal
- sedentary
- hibernation
- solitary
During the summer, Lampropeltis zonata becomes crepuscular or even nocturnal to avoid high temperatures during the day.
Behavior
The California mountain kingsnake is typically active from late March to October, but may become nocturnal during warm weather. It's a diurnal snake, but adjusts its activity pattern to avoid high temperatures.
This snake is usually found under woody debris and rocks in moist microhabitats. It's a secretive creature, spending most of its time underground, under surface objects, or inside rock crevices.
Lampropeltis zonata is a good climber, able to ascend over 1.5 meters above ground. It's not uncommon for this snake to be found coiled in a decaying cavity of an oak tree.
Here are some key behaviors associated with the California mountain kingsnake:
- terricolous
- diurnal
- sedentary
- hibernation
- solitary
The snake's activity pattern changes with the seasons, becoming crepuscular or nocturnal during the summer to avoid high temperatures. During the spring and fall, most daily activity is diurnal.
Predation
Lampropeltis zonata has a unique defense mechanism to protect itself from predators. It will first try to flee from danger.
This snake is vulnerable to a variety of predatory mammals and birds, but its bold and advertising pattern has been considered a mimic of venomous coral snakes, such as the Sonoran coral snake (Micruroides euryxanthus). This warning signal helps deter potential predators.
If Lampropeltis zonata can't escape, it may coil and strike its attacker. It will also twist violently to break free.
In the wild, I've observed that Lampropeltis zonata will release musk and fecal matter when threatened, which can be a strong deterrent to predators.
Conservation and Ecology
Lampropeltis zonata is listed as a California Species of Special Concern, and some populations are protected. This species is also protected in Oregon.
The IUCN Red List labels it as of Least Concern, which is a relatively stable conservation status. However, habitat destruction associated with urbanization and rock collection pose significant threats to this species.
Measures to prevent illegal snake collecting are weak in some areas, which is a major concern for conservation efforts. This species is capable of breeding in captivity, which could help fulfill the demand for pets while allowing native populations to remain undisturbed.
Here are some conservation and ecology facts about Lampropeltis zonata:
- IUCN Red List: Least Concern
- US Federal List: No special status
- CITES: No special status
- Habitat destruction threats: Urbanization, rock collection
As a key predator in its ecosystem, Lampropeltis zonata helps regulate the populations of its prey.
Ecosystem Roles
In the ecosystem, Lampropeltis zonata plays a crucial role as a key predator.
This means it helps keep the populations of its prey in check, which is a vital part of maintaining a balanced ecosystem.
Lampropeltis zonata is presumably responsible for regulating the populations of its prey, as mentioned in studies by Ernst and Ernst (2003).
Conservation Status
The conservation status of Lampropeltis zonata is a topic of concern. The species is listed as a California Species of Special Concern, and some populations are protected in Oregon.
Habitat destruction is a major threat to this species, particularly due to urbanization and rock collection.
The IUCN Red List labels Lampropeltis zonata as of Least Concern, but this doesn't mean it's not threatened.
Some areas where the species is found are protected habitats, but measures to prevent illegal snake collecting are weak.
Here's a breakdown of the conservation status of Lampropeltis zonata:
- IUCN Red List: Least Concern
- US Federal List: No special status
- CITES: No special status
