Upper-surface corridor, often branched and crossing itself, but not forming a secondary blotch. Frass mainly in thread fragments. Pupaption generally outside the mine. Sometimes pupation occurs within the mine, near the lower epidermis, but then already an exit slit has been made, and the spiracula do not penetrate the epidermis (Hering, 1924a, 1957a).

host plants

Lamiaceae, oligophagous

Melisssa; Mentha aquatica, longifolia, spicata, suaveolens; Monarda.


Larvae from April to October in several generations (Hering, 1957a).


BE recorded (Jean-Yves Baugnée, 2012; see also Mortelmans ao, 2014a).

NE recorded (Hering, 1957a).

LUX not recorded (Fauna Europaea, 2008).

distribution within Europe

From Lithuania to the Iberian Peninsula, and from the UK to Thrace (Fauna Europaea, 2008).


Described by de Meijere (1937a) and Spencer (1973b). Rear spiraculum with about 25 papillae.

parasitoids, predators

Hering (1957a) found the species to be common on Monarda, gone wild in the Amsterdam Hortus Botanicus. A pest on cultivated mint (Spencer, 1973b).
