Both larval and adult female L. trifolii feed primarily on the leaves of their host plants.
Larva feed mostly on the layer of the leaf just below the epidermis, while female adults feed on liquids expelled by the leaves after the adult has punctured them.
L. trifolii feed on a large variety of host plants, including both vegetables and ornamental plants.
Studies on the flies' preferred hosts show that some of L. trifolii's most preferable hosts are chrysanthemums, Gerber daisies, and celery.
When the females are placed on preferable hosts, they produce more holes and show an increased rate of oviposition.
