I don't remember this thread. Funny to find a quote attributed to me even though I was never here. Something posted about cocoonase caught my eye as being incorrect so I looked around for answers. After I found them, I also found that the incorrect info in the thread had also been corrected. Anyway, I found this info on cocoonase to be informative (study was done using polys): "Cocoonase is a trypsin-like protease used by certain silkmoths for their escape from the cocoon. Just before emergence of the moth (Days 17 to 18 of adult development), the enzyme can be collected with forceps from the surface of modified mouth parts, the galeae, where it occurs as a dry, semicrystalline deposit (l-3). An inactive form of cocoonase (2) begins to be synthesized 9 days earlier, by specialized cells of the galeae (4, 5) ; it accumulates within an intracellular vacuole, and eventually passes through special ducts onto the surface, where it is activated and concentrated. At emergence, the dry active enzyme is redissolved in a profuse solution of potassium bicarbonate (6) secreted by specialized salivary glands. The bicarbonate solvent adjusts the pH to the pH optimum of the enzyme (approximately 8.3), brings cocoonase in contact with the cocoon, and permits digestion of the "silk glue," sericin, to proceed. Once sericin is removed and the fibroin silk fibers are free, the moth pushes through and escapes to the outside." Here is a link that might be useful: Cocoonase study

I think I found my own answer. Wish I'd come across this website before. http://www.ipm.iastate.edu/ipm/iiin/node/144

It usually appears right side up in an app... but frequently not on the web version. Take all mobile and tablet photos in landscape mode, bottom of the phone/tablet to your right, and you will never have orientation issues. :) Never take them in portrait mode - most of the time they will end up appearing sideways to those viewing them in a web browser.

That isn't a bug, it is a cocoon/egg case. Take it off and squash it/throw it away; it will hatch into larvae/worms that will eat your leaves.
