15,000 photos. Wow, that is dedication.
For the diving beetle I like that you were able to capture what looks like the air bubble it uses to breath. Posted 3 months ago

  Thanks William...Yes, that's an air bubble! Not only can they trap air bubbles under their wings, but as a beetle uses up the oxygen in the bubble, oxygen from the water diffuses into the bubble as carbon dioxide simultaneously diffuses out of the bubble and into the water. Posted 3 months ago

  I happen to know that Christine is sitting on vast archives that are yet to be shared. Which is not true for me, I barely have any stock left. So it's only a matter of time.
  
  Which is good, I invite every member to outshare me, it's great for the platform. Posted 3 months ago

    Yes, but even with thousands of pics still in my archives, you will add many more new species than I will. Posted 3 months ago
