	abstract = {<p>In bushcricket communication systems males have to signal acoustically to attract females. The calling activity, however, not only may increase mating success, but also may result in costs in terms of energy and predation risks. In this study the calling activity of males and its timing during the day were analyzed for several species of the genus Poecilimon,representing two different communication systems. In species with mute females that approach the males phonotactically, calling was restricted to darkness and syllable rates were high. In species where females respond acoustically to male song and thus can induce the male to approach them phonotactically, males called during both day and night or during the day only, and syllable rates were low. After mating, male acoustic activity dropped to a very low level but was restored during the following 2 to 3 days, a time period longer than the minimal male mating interval. The results are discussed with regard to possible energetic limitations, the risk of attracting predators and parasitoids, and the spermatophore production of males.</p>
