They're on most leaves and they are leaving a discoloured yellow circle on the top of the leaf as well, even though they are firmly attached only to the bottom. These eggs(?) are light yellow with a hard coating and gel like stuff inside. Does anyone know what this is and if it's dangerous to the tree? Thank you |
