Eastern Collared Lizard

The Eastern Collared Lizard is a North American species named for the two bold black bands encircling its neck like a collar. With a large head and powerful jaws, it has a bold, sturdy look. Males display a striking blue-green body with yellow banding and a vivid yellow-orange throat, while females are brown overall and develop red or orange blotches, especially around the neck, when gravid. Active during the day, they are known for their agility and can even sprint on their hind legs alone when startled. Keeping this species calls for some intermediate-level husbandry knowledge, but its vivid coloration and distinctive presence make it a rewarding lizard for many enthusiasts.

About Eastern Collared Lizard

The Eastern Collared Lizard is a North American species known for its collar-like black bands and vivid coloration. Suited to intermediate keepers, it can live 10+ years with proper care.

7 things to know before welcoming a Eastern Collared Lizard

  1. 1A Warm, Arid Setup

    Eastern Collared Lizards come from sun-baked rocky habitats, so they need a strong basking spot reaching around 40°C with a clear temperature gradient across the enclosure. A UVB light is essential, and a dry, desert-style setup suits them best.

  2. 2Space to Grow Into

    Adults reach 20–38 cm in total length and are highly active, so they need a roomy enclosure. Since they love climbing and sprinting, give them plenty of floor space to move around.

  3. 3Bold and Solitary

    With a strong bite and a feisty temperament, Eastern Collared Lizards tend to fight over territory when housed together, so they're best kept singly. Once settled in, they often grow calm and confident around their keeper.

  4. 4An Insect-Based Diet

    These lizards are primarily insectivorous, readily hunting live prey like crickets. Dusting feeders with calcium and vitamin supplements helps keep their diet balanced and supports long-term health.

  5. 5Striking Color Differences

    Males show a vivid blue-green body with yellow banding and a bright yellow-orange throat. Females are mostly brown but develop red or orange blotches, particularly around the neck, when gravid.

  6. 6A Long-Term Companion

    With proper care, Eastern Collared Lizards can live 10 years or more, with records of individuals reaching 15 years. Be ready to commit to a long-term care plan before bringing one home.

  7. 7Setting Up Before Arrival

    Have a basking light, UVB light, thermometer/hygrometer, and hides ready before your lizard arrives, along with an enclosure with a proper temperature gradient. Since this species suits intermediate keepers, it helps to build up some husbandry knowledge first.
