|Mayflies, stone flies and sedges can be found on the River Nith to prompt trout into feeding. There will also be a variety of terrestrials although only the hawthorn, black gnats and daddy long legs are consistently important. The calendars below represent the times when these flies can be seen by anglers and available to trout. Anglers should remember that whilst we look for insects in the air, the trout are only interested in food. The majority of the food sources that the trout eat will be subsurface and nymphs. Shrimps and fish make up the biggest part of the trout's diet.||The calendars can be used to show types of nymphs that are available and most active. These are the ones which are closest to hatching.
Popular imitation patters for sedges include Hoolet, Hardy’s Favourite and Sedge Hog varieties. These also transfer as imitations for stone flies. March Browns and Sepia Duns are usually around earliest in the season whilst the biggest, the Great Red Sedge, emerges slightly later in the summer. Mayflies also appear around late June and July but the timing of hatches always depends on the weather during winter and early spring..
