The Large Yellow Underwing is a very common, large, brown moth, with orangey-yellow hindwings bordered with black.

It holds its wings folded back, flat along the body, and scuttles about on the floor like a mouse.
Adults fly from June right through to November, and often come to lights at night.

They rest during the day, but will flash their bright hindwings if disturbed to surprise and scare-off predators

The caterpillars feed on a wide range of plants, including grasses and Dock leaves, and hibernate over winter.

It is found almost everywhere.
