Rosy Rustic Hydraecia micacea
Wingspan 28-45 mm.
Common and widespread throughout the British Isles, this species has a wide variation both in colour and size.
It is on the wing from August to October and frequents waste ground, marshy areas, and other places where the foodplants grow.
The larvae live on a range of low plants, but especially dock (Rumex spp.), feeding beneath the ground on the roots.
