Rhyacophila larva

On a recent fishing trip I brought a couple of insect life samples to play with. I still need a (rather large) bit of practice to acheive the level of my aquatic macrophotography hero Jan Hamrský but I am starting to like my macro shots. A good first step :)

This is a Rhyacophila caddis fly larva, a subject dear to the heart of a fly fisherman (and to the stomach of a grayling fish). It is rumored these were the original inspiration for Czech and Polish style nymphs.

They have a tendency to form a curved position when disturbed, but rarely assume the C shaped position of a typical gammarus hook. Never the less, on streams where Rhyacophila are abundant a sickly green Czech style nymph will not disappoint.

Emerging Caddis

This is not a grayling fly, but  a wet trout fly. Especially targetted for a river I know that has a good population of sizable brownies. They seem hidden for the whole day, especially in the high summer, but become alive at dusk when the big caddis flies hatch.

With the low light the color of your imitation is becoming less important, and what matters is the general shape and movement of your fly.

Especially effective is the "rising caddis style" - a lightly weighted imitation fished sunk across the stream, with a gentle lift at the end of the drift. That is the moment when a violent strike is supposed to happen :)
