Being well into the grayling season and the rivers here in south Wales getting back to their normal height for this time of year, it’s time to start looking at the grayling. This weeks fly of the week is the Cased Caddis. A firm favourite as the heaviest or sacrificial fly on most grayling anglers casts. With very sporadic fly hatches this time of year most of the graylings feed is close to the bottom, you need something to get down there! View the video below to see how to tie a cased caddis.
First of all attach a tungsten bead to a kamasan b175 hook. Here I’ve used white UTC thread and built a layer behind the bead to secure everything in place. Run the thread down the hook to opposite the barb. Peal off a length of fine lead wire and wrap from the back of the hook, along the shank and tight against the bead. Break off each end and cover in a layer of thread. This stops any slippage.
Take a length of wool, green is a firm favourite of mine, but feel free to experimenting! Take a lighter and offer the wool to the flame, slowly so it doesn’t catch on fire, and wait until the end of the wool starts to burn. Gently blow on the end to extinguish the flame when you want. To the wool to the back of the hook, this represents the head of the caddis when its active, measure the length to around 1/3rd of the hook shank.
For it’s legs, take around 8-10 strand of pheasant tail fibres and tie in underneath the hook just a bit longer than wool tail and secure in.
Attach a length of gold wire to the hook and create a dubbing rope of Hares Ear. Keep the dubbing fairly tight and compact, your looking for a slim but tasty looking fly. Wind the thread to just behind the bead and run the wire rib through in the opposite direction. This gives the fly strength and robustness along with a great looking segmented effect. At the head, wind another turn or two of hares ear to the thorax to neaten things up.
