Anyone who lives near Lake Erie is familiar with the massive Mayfly hatches we endure each spring around this time. In the “nymph” stage, they can live under water for several years. As they mature, the metamorphoses of the nymph into a mature Mayfly happens over several stages of molts, and when they reach the surface of the lake, or river, they are winged little beauties that will live for only one day. Their only purpose at this stage is to mate and reproduce. It’s kind of sad when you think about it really, they finally free themselves of the water, and all that would gladly eat them, only to be able to soar like an eagle for one day, and then they die.
