Hatches on the Galloway rivers

For the majority of the fly fisherman who visit the Galloway rivers they will be reliant on mayflies, stone flies and sedges to prompt the trout into feeding. There will also be a variety of terrestrials about as well although only three - hawthorn, black gnats and daddy long legs - are consistently important. The calendars below represent the times when these flies will be seen by anglers and most available to trout. Anglers should remember that whilst we are on the lookout for insects in the air the trout are just interested in food.    The majority of the food items that the trout eat will be subsurface and nymphs, shrimps and fish will make up the biggest part of the Galloway rivers trout's diet. Assume the fish are feeding nearer the bottom on nymphs but the calendars can still be used as the types of nymphs that are available will be the ones that are most active and these are the ones which are closest to hatching. If in doubt you cannot go much wrong with either a GRHE or a PT when fish are seen to be feeding but on something that is sub-surface.

Popular imitation patterns for sedges include Hoolet, Hardy's favourite and Sedge Hog varieties. These transfer as imitations for stone flies also. You may find March Browns and Sepia Duns are around earliest in the season whilst the biggest of all the sedges in Galloway, the 'Great Red' sedge, emerges slightly later in late June and into July. May flies also appear around this time but always be aware that the timing of hatches overall depends on weather and climate conditions during winter and early spring.
