Description

The generic name of the dark crimson underwing moth, Catocala derives from the Greek 'katõ' meaning below, and 'kalos' meaning beautiful. This refers to the brightly coloured hindwings of underwing moths. The specific name sponsa means 'betrothed woman' or 'bride'; this may be a reference to the gaudy underwear worn by Scandinavian brides (1). The dark crimson underwing has mottled brown to greyish forewings which provide good camouflage against tree bark, and brilliant red and black-banded hindwings which can be suddenly revealed when the moth is threatened; this often startles predators such as birds. The caterpillar is grey-brown with raised red spots from which black bristles protrude (4).
