When fish are wary of brighter colours we have found this "leggy" green version of the popular squirmy worm is exactly what you need. Fished on either a floating line and retrieved with a jerky movement, or static under a Fario Bung you will find that the results can be devastating.
This fly also makes an amazing stalking bug for targeting fish - it has weight, movement and colour. We have had some fantastic feedback from customers about their results with this fly.
