    Oh wow, I've never seen such eggs at this extreme magnification. What are the white little bulbs for? Posted 6 years ago

      Hi Ferdy - it's frankly beyond the limits of my equipment and/or I should have been stacking those shots with at least 20 layers or so, but I still need to finish my setup with stepper motors for that *rolleyes* So, no more than a "feeble effort" to show some of the details of the structure.
      The "bulbs" are actually little tubes, called aeromicropylar processes (*yeahrightwhatever*) and I'm pretty sure they serve to let some air in (or out?), also for pressure balance or some such. To me, they are basically a great help in identification of eggs as they vary greatly in number, size, shape and structure between genera or even species, so I always try to make an effort and get at least _some_ idea of their basic shape (such as here).
      Here is a collage with similar *cough*close-ups*cough* of another species:
      Picromerus bidens - Eggs This species overwinters in the egg-stage. Eggs are deposited in fall, often behind bark or other "sheltered" locations.

        Very cool to learn that they have a function indeed. No need to apologize for equipment, you're already showing something very interesting, that I haven't seen before. These eggs seem so well defined, if you magnify them enough, it's almost like a building :) Posted 6 years ago
