A little delayed

Larvae. Lots of larvae. The yellow masses are eggs and young embryos. The brown masses in the foreground are larvae that are ready to hatch, and the little dots in the water are larvae that are hatching.

Yup. It's finally time to hit the experiments pretty hard, because I finally have the larvae I need. This is the great time of year, where nearly every female has larvae near-hatching. I took pretty much the same picture for you last year. Except I took it on May 26th. Cold weather = late snails.
