This widespread species occurs throughout the Palaearctic region from Western Europe to the far east of Asia including Japan, to the north reaching southern Scandinavia and occasionally further north, and to Turkey in the south. Typical habitats include wetland margins, marshland peat bogs and salt marshes etc, especially by stagnant still water with plenty of vegetation although adults may also occur under debris or among gravel and roots in freshly created habitats. Adults occur year-round; they become active in March or April and are generally present until October or November, peak numbers occur in May or June and freshly-emerged adults have been recorded from August until the autumn, these will go on to overwinter either in the soil or in litter among marginal vegetation or within stems of Typha latifolia (bulrush) etc. Upon emergence in the spring they feed on foliage and fresh stems of a variety of monocotyledons; Typha, Phragmites (reeds), Scirpus (rushes) and various Carex (sedges). Mating occurs in the spring and larvae develop through the spring and summer in the roots and lower stems of Typha latifolia, Carex acutiformis, and in other sedges and club rushes.

Snout long, black, curved downwards. Pronotum and elytra brown with small, yellowish spots. Antennae and at least partially legs brown. No spines on the fore thighs and shins.
