congrats Heppy!! neat to see the YP ribbons and where they end up. I had it once too that given a choice the YP would go into a structure (in my case the 6" round hole of a china made basket style minnow trap) It seemed they were happy to be become a 'cavity spawner' at that moment.

I don't know what all the white spots are in my floating/degrading YP eggs but there are a lot. Did you note white spots in each egg space too?
