Given that most of my Aquatic Biology course was spent flipping over rocks in running streams, I had completely forgotten that there are some insects whose aquatic larvae/nymphs prefer still water...
The pot to the left rear of the grouping above is the one with the damselfly nymphs--and no skeeters. The largest "pond" (out of shot here; largest pot in photo below) has mosquito larvae but no damselfly nymphs. Hmmm... *lol* Yes, damselflies and their heftier cousins the dragonflies are predatory. But I still want fish; oh, decisions, decisions...
