In Part 2 of Izaak Walton’s Compleat Angler (1676), Charles Cotton
  includes the dressing for the Orange Flie at the head of the list for July: “1.
  We have then the Orange Flie, the dubbing of Orange Wool, and the wing of a
  black feather.” Following suit in his reprint of Cotton’s flies, James
  Chetham includes the Orange-fly in his list of dressings for July in the Angler’s Vade Mecum (1681), although
  he inserts another fly ahead of it.  
In Fly
  Fishing: The North Country Tradition (1994),
  Leslie Magee reprints a pattern that is similar, including the Oringe Black in
  John Swarbrick’s “List of Wharfedale Flies” (1807): “The Flie is very
  Small a Hackle The feather is taken From a Starling Neck Harld at the Head
  with Marpie feather orange Silk.” This dressing is almost an exact match for
  the Orange Black No. 56 that John Turton includes in his  Angler’s Manual (1836). It
  is a silk-bodied dressing for July that Turton includes alongside the Wasp
  Fly, No. 57, which is dressed in darker orange-brown tones. 
Alfred Ronalds includes the Orange Fly, No.
  39, in his Fly Fisher’s Entomology
  (1836) as a dressing for a small orange scorpion wasp. He explains that it
  “is one of the best flies that can be used both for Trout and Grayling. There
  are a great many varieties, some larger, some smaller than the representation
  [on the color plate]. It may be used all day. Although discovered alive with
  difficulty, it is found abundant in the stomachs of the fish. It is furnished
  with an apparatus call the sting, used for the purpose of piercing the skin
  of caterpillars, in which it deposits its eggs, the grub from which grows in,
  and ultimately kills, the insect in which it was hatched. 
IMITATION. 
BODY. Orange floss
  silk tied on with black silk thread. 
WINGS. Dark part of
  the starling’s wing, or feather of a hen blackbird. 
LEGS. A very dark
  furnace hackle.” 
Michael Theakston, likewise, includes an
  Orange Brown, No. 83 in his List of
  Natural Flies (1843). In Theakston’s entomological parlance, a “brown” is
  a stone fly.

| This dressing uses silk buttonhole twist by Talon, orange 455, size D, and substitutes reddish brown cock hackle for landrail. | 
Theakston’s dressing calls for the Orange
  Brown to be “Hackled or winged with a landrail’s feather; bright orange silk,
  for body; with a few fibers of mohair or squirrel’s fur, at the breast.” 
In addition to representing a small summer
  wasp and a late season stonefly, the dressing also stands in for an the ant. Oddly
  enough, T. E. Pritt, in North-Country
  Flies (1886), traces the lineage of his Large Ant, No. 58, to the Orange
  Stinger that John Jackson dresses as No. 51 in his Practical Angler (1854). Jackson’s comment on the fly, however,
  and the dressing in particular align it more with Ronalds’ dressing for the
  small wasp than an ant: “This, though apparently a scarce insect, is greedily
  taken by both Trout and Grayling, from the middle of August to the end of
  September.” The dressing itself matches Ronalds’ almost verbatim. The
  “stinger” in the name, too, recalls the egg-laying stinger Ronalds describes.
