(I am a novice who hasn't had bees long at all)
In the 3rd picture I see some sort of (may not be the right terminology) queen, emergency, supercedure cell, or something like that. Maybe someone with some experience will be more detailed than I.
First off let me say this, I wear glasses for a reason. All of those cells looks a little funny to me. It doesn't look like "individual" cell caps. Sort of looks like they made one cap to fit all. could be the camera, could be the glasses, could be the eyes. Hopefully someone else can better explain it than I can. It may not be nothing.
