Larvae of tiny leaf-mining jewel beetle mine leaves and feed on their tissues, adults feed on leaves in the crown of trees.

The species is rare in the center, while on the northern city outskirts (on the territory of the forest park site) up to 10% of linden leaves were affected by mines of T. minutus.
