Morphology
underwing = wing (semi-transparent) = under + wing
The components 'under' + 'wing' are literal and recognizable, but the specific zoological sense 'a moth named for its concealed/hind wings' is specialized and not directly inferable as 'a moth' by a B1 learner. [Postprocessing: moved 'under' from base_words to prefix]
Etymology
Underwing comes from the two parts under ('below') and wing. It names the bright wing that sits hidden under the front wing of some moths and is suddenly shown to startle predators, so the word directly describes the moth's habit of hiding and then revealing its wing.
