Pests in Gardens and Landscapes

Grape leaffolder—Desmia funeralis

Moths of the grape leaffolder are almost black, with two white spots on the forewings and two white stripes across the abdomen. Larvae are translucent but appear greenish because ingested leaf tissue shows through the body wall. Small black spots, located above the second pair of legs, are present on later instar larvae.

Life cycle


Leaffolders construct leaf rolls and feed on leaves. Berries may be eaten late in the summer if worm populations are large and foliage sparse.


Remove suckers and thin leaves during the growing season to help remove leaffolder eggs. Handpick leafrolls. Several parasites, including the larval parasite Bracon cushmani, and many generalist predators attack grape leaffolders and may keep them under fairly good control. Applications of Bacillus thuringiensis or spinosad are also effective.
