The French Partridge series of fishing flies are characterised by their long head hackles of French Partridge, usually supported by a shoulder hackle and probably a palmered hackle. They are designed to imitate an emerging Mayfly, struggling to release itself from its shuck at the waters surface. They can be fished dry or damp but they are normally fished wet. The colour range is significantly geared towards the colours of the emerging insects and their nymphal colours.
