Abstract
ABSTRACT. The decticine bush cricket, Platycleis intermedia (Serville), can duet with, or be inhibited from singing by the song of P. affinis Fieber. Duets and inhibitions are sometimes alternated with perfect regularity. The normally homogeneous series of short echemes of P. intermedia can be thrown by the long emissions of P. affinis into an inhibition/excitation cycle involving post‐inhibitory rebound. The temporal characteristics of these interactions were accurately quantified. Time ‘lost’ singing was c. 85% of that ‘gained’. The coefficient of variation for syllables was far less than that for echemes, so that they appear to be controlled independently. Echeme duration, which is species‐specific, was the most behaviourally mutable song component. Such interspecific acoustic interactions illustrate the extent to which variation of song components takes place without involving long‐term changes in physiological and environmental conditions.
