This fly was created by Canon Greenwell in 1860. It is still as popular today as it ever was. This fly has stood the test of time for a very good reason; it works and it works well! This is a fly no river trout angler should be without.
The Large Dark Olive (L.D.O.) is one of the first flies to hatch on the river in spring. Often you can get L.D.O.s hatching on the opening day of the new season if the weather is mild enough. Other times it can be as late as April before they start hatching. Weather conditions will dictate when they start hatching. It is the most important fly for the dry fly angler for the months of March and April and again in September. A must have fly for any dry fly angler in Ireland or the UK.
Parachute dry flies are very successful river trout flies.
This one is size 14 to imitate the Large Dark Olive (baetis rhodani).
It will work well in both fast or slow water and trout will readily take it when they are feeding on emergers, duns or spinners.
The yellow foam post makes it very easy to see even in faster broken water and in low light.
