To get the best of any hatch, it’s vital we understand the life cycle of this unassuming insect. After hatching from eggs, miniscule nymphs spend one year beneath the surface developing.
As they grow these nymphs actually moult several times, very much like a snake that sheds its skin. In the life cycle Blue Winged Olives the sub imago is known as the “Dun” and the imago is known as the “Spinner”.
Three BWO Patterns For Your Box!
Come summer months, typically late June through to early September the now ripe nymphs swim to the surface to emerge into a dun (sub imago). You can visualize this as a butterfly emerging from its chrysalis. After their maiden flight, newly emerged duns take to the trees to undergo another transformation to the sexually mature adult, known in angling circles as “spinners”.
The spinner stage of BWOs is short lived, often 24-36 hrs. And mating within that short period, female spinners return to open water to deposit their precious cargo of eggs. Carried on the underside of their abdomen, these egg balls sink to the stream bed, or adhere to nearby vegetation, like submerged reed stems.
