Fig. 7. Long and short reply strategies of female Caedicia (traces 2 and 3) to a male call (trace 1) consisting of two parts B and C. Females producing a reply of six clicks have a low threshold at Y (high motivation), rising after recognising elements of part C of the male call (at X). These females call at the start of the species' specific reply window (shaded). Females with high threshold (low motivation) fail to call at the conclusion of part C and, following a brief silent interval, produce 1 or 2 clicks (at Z), which are timed from the conclusion of the call. Note that the click rate of trace 3 is faster than the rate for trace 2.
