I found this egg mass, while bailing my sailboat after heavy rains this week. I was stunned by its beauty and symmetry. The eggs are green, they are about 7mm x 12mm and are covered in a gelatinous coating that seems very much like the sort of coating we see in salamander eggs masses. The eggs themselves are minute, perhaps 0.5 mm in diameter. This mass appeared in my boat in between heavy rains; evidenced by the fact that I had bailed my boat only two days earlier. It was empty then and now the eggs are there. I suspect the mass was deposited by an insect, bt may be totally wrong. Any help is appreciated. Dragonfly? Damselfly?
