THE ENDRICK SPIDER IS ANOTHER OLD WET-FLY PATTERN. From what I can tell, it is of Scottish origin, but that’s of no importance: it will catch trout everywhere. John Shaner tied this fine example of the dainty Endrick Spider. Actually, because of the peacock-herl thorax, maybe it’s one step larger than “dainty.” It seems like more of an imitation of a small-to-medium sized emerging mayfly nymph, or perhaps a caddisfly pupa. While we often think of using sparse wet flies and spiders as a form of fishing practiced only in the United Kingdom, nothing is further from the truth. Many knowledgeable North American anglers routinely use wet flies; the silhouette of an insect struggling to the surface often overcomes the instincts of the wariest trout. American authors such as James Leisenring and Sylvester Nemes wrote about wet flies, and Dave Hughes and others carry on the tradition. These simple flies catch trout, and even novice anglers can quickly learn to use them. They are also extremely easy to tie, and by changing hook sizes and colors of materials, you can fill a fly box full of fish-catching patterns. Wet flies have been around for almost 200 years, and they will continue to be the cornerstones of many fly boxes.

The Endrick Water or River Endrick is a river which flows into the eastern end of Loch Lomond, Scotland.
Its drainage basin covers a large part of the west of Stirling District. The Burnfoot Burn rising on the southern slopes of the Gargunnock Hills and the Backside Burn rising on the eastern slopes of the Fintry Hills combine to form the Endrick Water which flows south before turning sharply westwards at the foot of the western dam of Carron Valley Reservoir. The river flows through Strathendrick, the village of Fintry and past Balfron and Drymen before entering Loch Lomond.The Endrick Spider is a simple pattern but is a very popular fly with fishers...
