Echo strength and detection distances (A) Spectral target strength (black line: mean, grey area: SD, n = 5) of five dried Y. evonymella with the wings in an upright position to represent a mid-flight moth. (B) Directionality of detection distance of the right-hand side of Yponomeuta evonymella based on echo target strengths over 180° in 0.5° steps (black line: mean, grey area: SD, n = 5), and sound produced by the moth’s wing-based tymbal during tethered flight in four orientations; 0°, 45°, 90°, and 180° (red circles: mean, error bars SD, n = 8, 80).
