Amauromyza labiatarum (Hendel, 1920)

Lamium album, Amsterdam

Ajuga reptans, Amstelveen, JP Thijssepark: frass pattern in the initial corridor
mine
The mine begins with a long, upper-surface, slender corridor. After a moult the larva changes its behaviour, and makes a large, upper-surface primary blotch without apparent feeding lines. Often the blotch overruns more or less of the initial corridor. Frass in the corridor liquified to form a wide green band, with a few tiny black granules along the sides. Pupation outside the mine.
host plants
Lamiaceae, broadly oligophagous
Ajuga genevensis, reptans; Ballota nigra; Galeopsis pubescens, speciosa, tetrahit; Glechoma hederacea; Lallemantia; Lamium album, amplexicaule, galeobdolon, maculatum purpureum; Leonurus cardiaca; Lycopus europaeus; Marrubium vulgare; Melissa officinalis; Melittis melissophyllum; Mentha; Prunella vulgaris; Scutellaria altissima, galericulata; Stachys alpina, germanica, officinalis, palustris, recta, sylvatica; Teucrium chamaedrys, scorodonia.
