It is one of the most common land planarians in human-disturbed environments in southern Brazil and is easily identifiable by the green color of its dorsum.

It is found in both native and disturbed environments, including seasonal and moist forests, as well as in human-disturbed areas, such as gardens, parks and plantations.

In laboratory experiments, it has been shown to feed on land gastropods, including species of environmental and economic concern, such as Bradybaena similaris, Cornu aspersum and Deroceras laeve.

[1] Once finding the prey, the planarian can try to immobilize it by muscular force and, if it succeeds, it everts its pharynx and begins to consume the gastropod.

[4] In order to ingest snails and large slugs, O. ladislavii pierces the prey's body with its pharynx and sucks its contents, apparently after releasing digestive enzymes.
