Phytomyza chaerophylli


    The larvae of the fly Phytomyza chaerophylli mine the leaves of umbelliferous plants such as Cow Parsley. The mines often follow the margin of the leaf at first, but the mined area can easily form a blotch that covers a wide area of the leaf. The mine is pale and frass occurs in two untidy rows of isolated grains. The mine is seen more frequently than the adult fly.
