body, orange silk, waxed, with a few fibres of red brown 
mohair at the breast. 
47TH.—EARLY SPINNER.—Full length, near three-eighths ; 
length, better than one-fourth ; wings, full one-fourth, fine 
and clear, veined lengthways, and tinged light brown; 
thighs and legs long and small, of a dull reddish trans- 
parency ; is a very slender fly; hatches this month, and 
continues through April; body and shoulders a light leady 
grey color. 
Winged or hackled with a feather in the redwing’s wing; 
body, yellowish, ashy silk ; legs, a dark red brown hackle ; 
must be dressed very small and slender. 
5TH.—GRAVEL SpINNER® (Spider Fly).—Full length, 
about a quarter of an inch; wings lie one upon another 
over the back, and extend a little beyond the body; they 
are fine and clear, but when closed have a darkish blue 
shine upon them; body, a dark ashy, leaden hue, rather

This description is of the early hatchings of the gravel 
spinners, just after they come out of the water. In the 
beginning of May they assemble together in great numbers, 
on dry sand beds by the water sides, where they may be 
(8) Mr. Ronalds speaks very highly of this fly, which is however not found 
upon all streams. I have generally found it kill best under the conditions named 
by him, viz., in May (the latter part) when the weather is bright and the water low 
and clear. Mr. Aldam, in his unique work on artificial flies, recommends for the 
wings a covert feather outside a woodcock’s wing, next to the quill feather, and this 
imitates the natural fly very well. The same authority also states that this fly, in 
its earlier stage of existence, is not known much to the fish, but that later in the 
season, when it has grown larger and richer in colour, it is taken with avidity both 
by trout and grayling, the latter fish however not being fit to take at that season of 
the year.
