Phytomyza marginella


    The larvae of the Agromyzid fly Phytomyza marginella produce a corridor mine in the leaves of various plants including Dandelion. The first part consists of a very long and narrow lower-surface corridor; the mine is quite shallow here, and often inconspicuous. The second part is upper-surface, usually much shorter, and widens abruptly.
