Range
Originally from central Europe, now from UK to Siberia and recently in the Northeast USA.
Season
Spring and fall as adults, summer and winter as pupae
Food
Larvae mine leaves of Allium, most often leeks because leaves are available during both flight periods.
Remarks
Other leaf miners in Allium are species of Liriomyza with yellow scutellum. They do not cause wilting leaves.
