In Belgium, only known from an old record (Kalmthout, AN, 1900-07-24, leg. De Crombrugghe). The species was never mentioned again in Belgium. Very probably extinct. The species seems to be declining everywhere in Europe.
The early stages have not yet been described. Pupation is supposed to happen in the water since a freshly emerged adult was observed drying its wings on a plant completely surrounded by water. The adults are mostly seen flying over banks of brooks in late afternoon.
Probably two, difficult to separate, generations a year: from June to September.
There is no information about the larval foodplants, but it may be asumed that it must be some aquatic species.
Marshes, brooks, moors, river banks.
