Horn Cased Caddis Nymph

Horn Caddis nymphHorn Caddis Nymph

Caddis flies come in many different sizes, colours and shapes. They may not be that glamorous as a trout fly but this larval stage of the insect’s development provides head waters trout in particular with a vital food source.

The brown horn shaped case isn’t very big; perhaps 10mm or so. They cling to rocks and stones so generally should be fished close to the bottom. For this reason your Horn Cased Caddis Nymph imitation really needs a bit of extra weight to make it sink. The usual method of adding weight is to wrap a little lead around the hook. You can also use copper wire to form the tapered shape of the body. Nowadays many tyers prefer to improve the sink rate of their Horn Caddis imitations by using a tungsten bead at the head.

My version here has been created with brown floss over fine lead wire. The head is of dark grey wool with just a little teased out with a bodkin to suggest the insect’s legs poking out of its case.

The Horn Cased Caddis Nymph is really a pattern for spring creeks and river headwaters best fished by casting upstream and bringing it back close to the bottom. It also makes a good dropper when fished with a dry fly which can be used as an indicator with the potential to be taken as well of course.

Hook size: 8 – 14.

Body: Brown floss over lead wrapped around hook. Head of dark grey wool.
