The mine begins as a small upper-surface blotch, from which corridors radiate. Wile these become longer and more numerous a secondary blotch develops. Frass in pearl strings. Pupation within the mine. The front spiracula of the white puparium penetrate the plant epidermis.

In small plants the larvae can also mine the stem (Buhr, 1964a).

Beri (1971e) describes the larva from an unidentified Lamiaceae in India. It is most improbable that his identification is correct.
