These are the eggs of an Anglewing Katydid which you can verify by comparing your image to this BugGuide image. Adult Anglewing Katydids resemble large green grasshoppers, but with very long antennae, and they have wings that help camouflage them among the deciduous leaves that they feed upon. Anglewing Katydids are solitary feeders and they do not harm trees because of the few leaves they eat. Males call to the females and the “song” of a Katydid is a welcome summer night sound.
