Apamea monoglypha (Hufnagel, 1766)

Host plants:
The larva feeds on grasses. I found some caterpillars on Deschampsia caespitosa on moist forest clearings, on Dactylus glomerata in a garden and quite often Festuca ovina agg. (F. guestfalica) on rocky sites with Spiris striata.

Habitat:
Apamea monoglypha inhabits grassy habitats of all kinds and is ubiquitous.

Life cycle:
The caterpillar overwinters. It lives in a webbed cave in the base of grass clumps and pupates until early or mid-June. Moths appear from late June to late August.

Remarks:
Apamea monoglypha is widespread and often common in Europe and temperate Asia to the Altai.
