Willow Grubs are larvae of the willow gall sawfly, Many lose their footing during feeding in summer and fall into the water. Trout inhabiting lowland streams and rivers have learnt to take advantage of this seasonal food source. Lining up under the willows they either rise to take the little grubs in the surface film, or are content to feast on those that have sunk. Fish rising below willows in summer with no evidence of a hatch is good indication that they are eating floating grubs.
