Flashy Blue Head Damsel
The Damsel fly like many lakeside insects begin their life underwater as a nymph, these nymphs are carnivorous critters feeding on a wide variety of small underwater life forms such as daphnia and buzzers.
During its life as a nymph they moult several times before they begin their final metamorphosis. Swimming in the margins of the lake they identify structures entering or exiting the water. Once a bull rush or wooden jetty has been found they will scale it, crawling up until they are fully out of the water. It is only then safe from the haven of the water that the nymph will then hatch. Emerging from it’s casing into a fully winged adult Common Bluetail Damsel.
It is prior to this hatching period when the nymph is most vulnerable to the feeding Trout, as it leaves the safety of the many hiding places on the floor of the lake to find it’s hatching vantage point.
Best fished: With this fly I like to build as much variation into my retrieve as I possibly can to bring the marabou tail of the fly to life. The hot blue head on this fly works in tandem with the tail as an irresistible mouthful for the resident Trout. So work that fly with jerky pulls mixed with speeded up figure of eight retrieve for savage takes.
