NOCTUIIDAE
Hypena bijugalis
Most snout moths (named for the long palpi),
genus Hypena, are greyish and rather undistinguished. I had no idea
until I saw this beauty that any of them were as strikingly marked as Hypena
bijugalis. A neighbour brought me the pupa of this moth, so I have no personal
knowledge of the larval foodplant , though it is listed in books as dogwood
(Cornus). Apparently only the female is strikingly marked like this
one. The male is the usual undistinguished greyish brown. Perhaps the striking
markings of the female are an example of “disruptive coloration”,
in which the sharply contrasting colours disguise the shape of the insect.
