Phytomyza salviae (Hering, 1924)
Upper-surface corridor. The first and last part are rather straight, but the middle section is so densely wound that a secondary blotch results, with clear primary and secondary feeding lines. Frass in pearl strings. Pupation external.
The association with Ballota has only been seen in Russia. In western Europe Salvia verticillata is the main hostplant.
