Mayfly

Suborder PannotaSuborder Schistonota Bloodless and many footed animals, whether furnished with wings or feet, move with more than four points of motion; as, for instance, the dayfly (ephemeron) moves with four feet and four wings: and, I may observe in passing, this creature is exceptional not only in regard to the duration of its existence, whence it receives its name, but also because though a quadruped it has wings also.The River Bug on the Black Sea at midsummer brings down some thin membranes that look like berries out of which burst a four-legged caterpillar in the manner of the creature mentioned above, but it does not live beyond one day, owing to which it is called the hemerobius.Myriads of May-flies appear for the first time on the Alresford stream. The air was crowded with them, and the surface of the water covered. Large trouts sucked them in as they lay struggling on the surface of the stream, unable to rise till their wings were dried... Their motions are very peculiar, up and down for so many yards almost in a perpendicular line.In shoals the hours their constant numbers bringLike insects waking to th' advancing spring;Which take their rise from grubs obscene that lieIn shallow pools, or thence ascend the sky:Such are these base ephemeras, so bornTo die before the next revolving morn.
