Halford's Willow Fly

This family of stonefly is fairly slender by stonefly standards. The divergent wing pads are a helpful characteristic. Leuctridae are similar in overall shape to the Capniidae; however, Leuctridae often do not have pleural folds. If they are present, they only extend from abdominal segments 1-7. The genus Leuctra are recognized by abdominal terga with posterior fringes of short hairs and last few segments with longer hairs.
