Sandys Straggle Rhyacophila Step by Step
Friday, 20 June 2014 | Admin
The Rhyacophila, well known by knowledgeable fly fishermen is the free swimming larva of a green sedge and is best fished close to the riverbed. Large, usually apple green, and always plump, and they don't build cases or nets. Rhyacophila roam freely about the fast water and they often drift loose, where they are a good food for trout. Many of these larvae have no gills at all and rely on absorbing oxygen from the water through their skin. Only cold water and fast flows can meet these needs, so Rhyacophila caddis flies love the same habitat as trout, useful for fly fishermen!
The larvae may rappel between the rocks on a line of brown silk they secrete. A fly fisherman can imitate this by colouring the last foot or so of one's leader with a brown marker. Fly tying a deadly Ryhacophila larvae imitation is simple with Semperfli's Straggle String Gary LaFontaine wrote some good tips in his book Caddis Flies about fishing appropriate flies for the water you're covering: "A good imitation of a Rhyacophila larva is going to catch a lot of trout in swift, bouncing stretches of stream. The same fly is going to do poorly in slow areas of the same stream. A fly fisherman can avoid wasting time in the wrong sections of a stream by working leap-frog fashion instead of in a straight line. If he is using an imitation of a fast-water insect he should fish only the swift, broken currents, skipping past the slower current areas. Likewise, if he is using an imitation of a slow-water insect he should only cover the quieter pools and flats." This is an idea fly in late autumn and in early spring as the Grayling are into the faster riffles where Rhyacophila are prolific.
Sandy Dickson's Deadly Rhyacophila Nymph
Tying The Deadly Sandy's Straggle String Rhyacophila - An ideal autumn and spring fly fishing fly for use on swift rocky water. This is an extremely simple fly to tie but extraordinarily effective imitation of the Rhyacophila larvae. It uses Semperfli Straggle String for the body which has UV strands which look like legs moving. Added to the colour of the Straggle String SF7250FL matching the Rhyacophila larvae perfectly, used on fast bouncing stretches of water this is a deadly fly.
