This generic nymph can be dressed in various sizes and colours to suit your own needs. Obviously a size 14 or 16 olive bodied pattern sporting a dark bead is well suited to copying the many baetis nymphs found in our rivers. A size 12 fly using a mahogany biot is more than suggestive of stoneclinger nymphs that frequent the faster parts of a stream.
Whilst biots are more commonly used for stonefly nymph tailing fibres or the wing buds on buzzer patterns they've great value when wound as a body on smaller nymphs. In fact with one raised edge these make the most spectacular segmented bodies not just on nymphs but dries too. Of course, as right handed tiers, we need to take a biot from the right wing of a turkey or goose to achieve the correct profile. Conversely those who dress flies left handed should take a fibre from a left wing.
Flecked and almost transparent Coq-de-Leon feathers make great tailing fibres and are nigh on indestructible too. A layer of varnish over the thread base prior to winding the herl body helps make this more durable. A pair of hackle pliers provide a great purchase when forming this body and help achieve nice even turns.
Depending on whether you opt for a bright bead, or one with a subdued finish, determines what colour of thorax is best. If using a gold or copper bead then I'll select a sombre shade of dubbing. When incorporating a black or gunmetal coloured bead, something with a hint of flash, or a little more garish like orange or pink makes an attractive alternative.
