Which marsupial uses a stick to extract insect larvae from tree bark?

Which marsupial extracts insect larvae from tree bark? The answer is the striped possum.

The striped possum (Dactylopsila trivirgata) is an arboreal marsupial found in New Guinea and northeastern Australia. It specializes in feeding on wood-boring insect larvae hidden in rotten branches and tree bark.

It locates larvae by tapping on wood and then excavates the bark with powerful incisors. Its unusually elongated fourth finger, equipped with a hooked nail, helps probe cracks and collect insects.

The question’s reference to a stick is inaccurate: the possum’s specialized finger is the relevant tool. Stick-based larva extraction is better known from New Caledonian crows, which are birds rather than marsupials.
