A Dark Spanish Needle pattern of John Swarbrick, Wharfedale Flies (ms. 1807, published 1907). Offered by Swarbrick as a small stonefly nymph.

Thread: Orange silk
Wing: Feather of a wood owl wing
Head: Peacock herl
Being permanently short of owl skins, I substituted English woodcock. The same basic fly is repeated many times in books after 1807 (sometimes with new names), but I've not found an earlier version. Anybody know of one?
This variation is tied with peacock as a thorax instead a head:

I like the look, and the tie is a bit less fussy. Anybody seen this pattern in the literature? I cannot find one.
