little worms on grapevine
I think you guys are great. I would love to know what these little worms are. They really don’t seem to move, but I’ve found evidence that they’ve been around. Where did they come from and do they need to be destroyed or do they turn into something good? I found them on my grapevine. Thanks,
These caterpillars are Grape Leaf Skeletonizers, Harrisina metallica. The caterpillars are a major defoliator on grape vines.
