Grape Plume Moth, Geina persicelidactylus (Fitch) (Lepidoptera: Pterophoridae)
The grape
plume moth overwinters in the pupal stage. Adult moths emerge during the spring
and lay eggs on grapevines. Hatched larv
ae
feed on the upper grape leaf surfaces. Typically, a grape plume moth larva folds
and webs the edges of a terminal leaf together and feeds within the fold. The
larva is yellow with white hairs and about 5/8 inch long when fully grown. The
adult moth is light brow
n
with whitish markings and is 1/2 inch long. There is one generation each year.
Plume moth larvae rarely occur in large enough numbers in commercial vineyards to justify control measures.
