Calycomyza artemisiae


    The larvae of the fly Calycomyza artemisiae mine the leaves of Mugwort.  The mines are seen more often than the adult. The mine is a characteristically pale whitish, usually upper-surface primary blotch. There is an initial corridor, but traces of it are almost always overrun by the later blotch. The mine is quite opaque.
