It is most likely that since they were first little black things in clear stings they are toad tadpoles. Toads lay their eggs this way - eggs distributed singly in narrow diameter clear gelatinous tubes. Another good indication is they occurred in MI during the first days of May which is about 2 wks after toads hatched in northern OH. Hatchling toads and frogs (tadpoles) are only the length of the diameter of the egg.
