Hi Jorge and friends,
As the title says, I have no idea what these are. They are about 1 mm or less in diameter and are clear or translucent. They are on the leaf stems and come off easily and don't leave a mark where they were. They are hard and seem hollow and crush easy....almost like a small sugar egg. Some seem to have a hole in the side. I've done a ton of research but have found nothing. I have inspected diligently and have no sign of any pests. Anyone seen anything like this. Thanks for any info. Pics are attached, but kinda blurry because they are so small.
