A friend reported she saw the adult grapeleaf skeletonizer flying around her grapes in the Summerlin area of Las Vegas. You should begin looking for the adult which is a nearly black, unusual-looking moth near grapes.
Adult will lay eggs on the UNDERSIDES of leaves so you must look on the bottoms.
The young, larvae, are small “worms” that hatch from the eggs in about 7 to 10 days. This young worm stage is when they are most easy to control with sprays even insecticidal soaps.
Use sprays like Bt, Spinosad, insecticidal soap, …..Sevin, and general fruit tree insect sprays if you garden conventionally.
