The specific name, wiegmanni, is in honour of German herpetologist Arend Friedrich August Wiegmann.

It is commonly seen in the leaf litter of shady rain forests.

[5][6] When perceiving danger, O. wiegmanni spurts away quickly on its large hind legs and might eventually climb up a sapling or tree.

[5][6] O. wiegmanni feeds on small insects, grubs, and tender shoots.

[5][6] O. wiegmanni is closely related to the Indian kangaroo lizard (O. beddomii ) of the rain forests of South India.
