underwing
Noun 1. A type of moth: An underwing is a moth belonging to the genus Catocala or related groups, characterized by having forewings that are camouflaged (often dull-colored) and hind wings that are conspicuously colored, typically in shades of red, yellow, or orange. The bright hind wings are usually hidden when the moth is at rest.
The word "underwing" is used specifically as a common name for these moths. It is typically used in singular form to refer to an individual moth or in plural form ("underwings") to refer to multiple moths or the group as a whole. - An underwing was resting on the tree bark, perfectly camouflaged. - The underwing flashed its bright hind wings when it took flight. - We observed several underwings during the night survey.
- The term can be used in a more general descriptive sense in entomology to refer to the characteristic of having differently colored hind wings, though this is less common.
- The underwing pattern is a classic example of defensive coloration.
- Underwing moth: A more explicit, compound form of the common name.
- Catocala: The scientific genus name for most moths commonly called underwings.
- Catocala moth (scientific context)
- The word "underwing" in this context is a closed compound noun. It should not be confused with the separate words "under" and "wing" used in other contexts (e.g., "the under wing of the aircraft"). In this zoological sense, it refers specifically to the moth.
- moth having dull forewings and brightly colored hind wings
