Grapeleaf Skeletonizer – Harrisina Americana

Grapeleaf Skeletonizer – Harrisina Americana Common Name: Grape leaf Skeletonizer Latin Name: Harrisina Americana Appearance: The Grape leaf Skeletonizer larvae are black with yellow stripes, while the adults are grey-brown moths with a wingspan of about 1.5 inches.
  • Eggs:Small and light in colour, the eggs are placed in groups on the undersides of the leaves.
  • Pupae:The pupae are brown and are usually found on the host plant or nearby vegetation.
  • Larvae:The larvae feed on the undersides of grape leaves, leaving a skeletonized appearance.
  • Adults:The adult moths do not feed and only live for a few days to mate and lay eggs.
Host plants: The Grape leaf Skeletonizer primarily feeds on grape plants but can also infest Virginia creeper and other related plants. Territory: The Grape leaf Skeletonizer is found in eastern North America, from Canada to Florida. Damages caused by Grapeleaf Skeletonizer: Grapeleaf Skeletonizer larvae can cause significant defoliation of grape plants, leading to reduced grape yields and fruit quality. Life history and habitat: The Grape leaf Skeletonizer overwinters as pupae in the soil, with the adult moths emerging in the spring. The female moths lay eggs on the undersides of grape leaves, and the larvae feed on the leaves for several weeks before pupating and emerging as adult moths. The Grape leaf Skeletonizer is most commonly found in vineyards and other grape-growing areas and in natural habitats such as forests and woodlands.
