Hy, I am Don from Franklin, La, and I have a second year growth of Thompson White Seedless grape vines that have and still has this pocket of caterpillars, they start with a group of egg pockets cluster about the size of a quarter and grow to small caterpillars and eat away at the leaves, I sprayed with daconil and also use seven dust (which is better) than daconil. What is it and what is the best control? I also saw a leafhopper.
These are Grapeleaf Skeletonizers, Harrisina americana. The caterpillars will eat the leaves to the veins. We don’t provide extermination advice.
