Mine: Spring and summer

Notes: Found most commonly on Taraxacum officinale . The mine illustrated is from Sonchus. Forms a white mine along the midrib, wth side branches into the leaf blade, with little frass in the galleries. Pupation occurs at the base of the midrib. Adult emerged 15.vii.2021. The mines of O.beckeri and O pulicaria are similar and so the adults must be bred to identify the leaf miner.
