After hatching young larvae penetrate into leaves, fruits, buds and stems to feed within galleries or blotch like mines. Leaf mines contain darker frass and become necrotic. Stem galleries prevent plant development. Larvae prefer to attach apical buds, flowers and fruits. Larvae do not attack potato tubers.
