Rivula sericealis (Scopoli, 1763)

Rivula sericealis: Adult [S] Rivula sericealis: Adult (e.l. Memmingen) [S] Rivula sericealis: Half-grown larva [S] Rivula sericealis: Larva [S] Rivula sericealis: Larva (Memmingen) [N] Rivula sericealis: Pupa [S] Rivula sericealis: Pupa dorsal [S] Rivula sericealis: Habitat at the time of the hibernated young larva in the March: many observations of larvae (Stuttgart, 2009) [N]

Host plants:
The larva feeds on grasses. I found caterpillars on Calamagrostis sp. and Brachypodium sylvaticum.

Rivula sericealis inhabits extensively managed and higher growing meadows, grassy edges in open areas, along streams or in the forest. I observed larvae in a clear floodplain forest (Iller valley in Southern Germany) at the edge of an afforestation, in a seasonally dry, quite nutrient-poor, grassland-like oak grove and in Ticino in the Maggia delta on grassy spots.

Life cycle:
The caterpillar overwinters. It is fully-grown in May. The moths fly from June to August in a single or in warmer areas from late May to September in two generations.

Rivula sericealis is widespread in Europe.
