The varying plant life and wildflowers within sand dunes attract many insects, including pollinators. The Grayling butterfly can be seen in dune habitats camouflaged amongst woody plants, rocks and sand. Its wings are closed when not in flight but will open to reveal pale bands on the upper wings and orange eyespots.

The Grayling butterfly will lay its eggs on various plants within the dune habitat and occasionally can be found on marram grass. The caterpillars will then feed on the marram grass until they pupate.
