The very warm weather of early March started mating season of the Wood Frog (Lithobates sylvaticus) and egg masses were soon found in many of the pools of water. The newly laid frog eggs looked like black dots surrounded with a clear "jelly".
After a couple of weeks, the black dots of the frog eggs have changed to elongated objects with a bump for a head and a tail that is starting to twitch.
This photo of frog eggs was taken when they were laid early in the month. Today, when I check the frog eggs in this pool of water, I found hundreds of small tadpoles were starting to hatch and swim around.
