A very rare species in Belgium, not seen for a very long time.
Native
Wingspan 14–16 mm. The moderately conspicuous whitish antemedian patch on the dorsum, the small but distinct whitish postmedian spot only a little below the costa and the characteristic prominent pale yellow tornal spot distinguish this species.
The caterpillars only inhabit the lowest stalk link between the root and the lowest stalk node.
Two generations a year from April towards June and in August.
The larva lives on Impatiens noli-tangere.
It inhabits marshes and riverbanks.
