The three ♂ 06R interval patterns were recorded during three consecutive 12 hour periods. The ratio of monophasic to varied beat-interval call patterns for 06R (blue) = 7:3, 06R (red) = 5:5, 06R (green) = 3:7, and 07C (purple) = 8:2.Published as part of Sandberg, John B., Serpa, Larry E. & Drake, Eugene F., 2015, The Drumming Signals Of Three Winter Stonefly Species (Capniidae, Leuctridae: Plecoptera); With Discussion Resolving Two Common Interval Patterns, pp. 51-74 in Illiesia 11 (6) on page 68, DOI: 10.5281/zenodo.476093
