Liriomyza bulgarica Beiger, 1979
mine (from Ostrauskas, Pakalniškis & Taluntytė)
Initially a corridor on top of the midrib, later widened into an elongated blotch with many, irregular side branches that are not strongly determined by the leaf venation. The mine invariably contains several larvae. Fras in irregular grains and strings. Pupation outside the mine. Contrary to L. strigata the mine is not preceded by a narrow lower-surface corridor.
Sonchus arvensis, asper, oleraceus.
Larvae in June.
