Something is eating the leaves of my White Potato Vince (Solanum Jasminoides). I have seen small moths, also larvae hanging from a single web. I'm guessing size to be between 1/4-1/2 inch. Also, probably their droppings in massive quantity, look like pepper, but feel like sand under bare feet. When washed away with the hose, it turns the water green. Since my vines are on a trellis, up high, I have been using a pressure nozzle on the hose, hoping to blast them of the vines. The underside of the vine is now barren of leaves and looking rather sad.
