Phytoliriomyza clara
Phytoliriomyza clara is a species of leaf-mining fly in the family Agromyzidae, first described by Melander in 1913. It is known to feed on bracken (Pteridium aquilinum), making it a specialist herbivore of this widespread fern genus. The species occurs in North America, with records from Canada and the United States. Like other members of its family, it likely produces characteristic serpentine or blotch mines in host plant foliage during its larval stage.
