Mine: Spring and summer

Notes: Found most commonly on Taraxacum officinale . The mine illustrated is from Sonchus. Forms a white mine along the midrib, with side branches into the leaf blade. Pupation occurs at the base of the midrib. Adult emerged 02.viii.2017. The mines of O.beckeri and O pulicaria are similar and so the adults must be bred to identify the leaf miner.
