Brassie
A minimalist and heavy nymph fly, primarily designed to mimic various species of small aquatic larvae.
How it's tied
The Brassie is tied on a short-shank hook, typically in sizes 18 to 22. It features a slim, cylindrical body made from tightly wound wire—usually copper or brass, hence the fly's name. This construction gives the Brassie its characteristic weight and flash, allowing it to sink quickly and catch the light underwater
The thorax of the Brassie is usually made from peacock herl, giving it a touch of iridescence and natural appeal. A simple thread head completes the fly, followed by a whip finish and head cement for durability..
Despite its simplicity, achieving a neat, even body with the wire can require a certain level of skill, as can tying in the delicate peacock herl without damaging it.
What it mimics
The Brassie is a versatile pattern that can mimic various small aquatic larvae, such as midge or caddis larvae. Its slim profile and the flash from the wire body can make it particularly effective in mimicking midge pupae or small mayfly nymphs.
Where it's used
The Brassie is a valuable fly in a variety of water types. It can be used in rivers and streams, where its weight helps it get down in faster currents, and it can also be effective in still waters like lakes and ponds, especially where you need to get your nymph deep quickly.
