Lace Monitor

Did You Know?

  • Live for 10 - 15 years on average (some captive animals reach 40 years of age
  • If females are unable to find a termite nest to lay eggs in, she will create a nest in a hole in the ground filled with grass and leaf litter to incubate the eggs while they decompose

Found in two broad forms. The main form is dark grey to dull blueish-black with numerous, scattered, cream-colored spots. The snout is marked with prominent black and yellow bands extending under the chin and neck. The tail has narrow black and cream bands which are narrow and get wider towards the end of the tail.

The other type, known as Bells form, is typically found in dryer parts of NSW and Queensland. It has broad, black and yellow bands across the body and tail. Close up, these bands are made up of various spotted patterns.

Also known as the Tree Goanna.


About 55cm long (head and body); 140 cm long (head to tail). Some may grow up to 2.1 m long (head to tail).



The Diet of the lace monitor is varied, including insects, other reptiles, small mammals, birds, eggs and carrion (dead or decaying flesh).


Terrestrial and often arboreal (tree dwelling), an active lizard that forages over large areas.


Mating takes place in Spring and Summer where males will gather around and mate with receptive females. The female lace monitor will lay between 6-12 eggs, usually laid in termite mounds.

They reach sexual maturity at about 4 - 5 years of age.
