Phytomyza mylini Hering, 1954
The mine begins as a narrow corridor along the leaf margin. This widens into an upper-surface blotch, that almost invariably contains some elliptic full depth patches. Frass irregular, grains closely together, sometimes partly in pearl chains. Pupation outside the mine. Beiger (1960a) presents an illustration.
Hering (1957a) also mentions Seseli libanotis as a possible host plant; this was based on a somewhat uncertain observation under semi-natural circumstances (botanical garden). However, Beiger (1960a) mentions mylini from another Seseli species, viz., S. montanum. Recently also reared from Cicuta virosa (Pakalniškis, 2000a).
Larvae in May-July (Hering, 1957a).
Not known from the Benelux countries (Fauna Europaea, 2008).
