No. 15 The Jenny Spinner
This is the name of the iron blue dun (No. 14) in his new dress, in which he lives four or five days. It is a killing fly towards evening in clear water in summer. There are in the United States at least some hundred varieties of these small ephemeridæ, of every conceivable color, and the skilful dresser will take pleasure in tying them, using the feathers of the small domestic and foreign birds which he can procure. Such are the sky-blue, the orange dun, the pale evening dun, the July dun (blue and yellow), the whirling blue dun, and the little pale dun.
Imitation
