The posterior pair of wings are put on first, and the anterior afterwards. As the mode of procedure is practically the same as in the Blue-bottle, with the addition of another pair of wings, I need not enter into further detail.

The Willow-fly, when it falls on the water, has its wings sometimes in one and sometimes in the other of these positions.

Body. Light brown fur from water-rat, ribbed with narrow gold tinsel.

Hackle. Ginger.

Wings. Darkest starling’s quill feathers. The wings should be made narrow.

Hook. Nos. 00—1, new size.

The Yellow Sally (Chloroperla grammatica, Poda).

This fly appears in May and June, and though it is said to be occasionally taken by trout, does not seem to be relished to any great extent by them. The wings should be placed one over the other as in the illustrations of the imitation fly given on [Plate II].

Body. Light brown water-rat’s fur, ribbed with yellow silk.
