Dark arches

The dark arches is the common name for Apamea monoglypha, a widespread noctuid moth in Europe. It is especially notable because its larvae feed underground on grass roots.

The larvae feed on grass roots below ground. This habit can make them a frequent and sometimes damaging presence in grasslands, lawns, and gardens.

Their caterpillars remain underground and feed on roots, so plant damage may appear before the larvae are easily seen. Grass and other plants can weaken when their root systems are attacked.

Yes. The dark arches is described as one of Europe's most common and widespread noctuid moths. Its broad distribution is linked with the availability of grassland and other suitable larval habitats.
