Oviposition at the underside of the leaf, in an axil of the midrib. The larve starts by making a lower-surface blotch, but then works itself to the leave’s upper surface and makes an upper-surface blotch on top of the midrib. The blotch is elongate with lobe-like extensions, and whitish in colour. Larva solitary. Pupation external.

North American species, that made its appearance in Europe in 1970 near Milano. Now widely distributed in south and central Europe, seemingly expanding towards the NW. Considered a pest in southern Europe because Acacia is an important nectar source for commercial apiculture.
