Behaviour

single male of C. deciduus was field-recorded then collected as it sang from a tree branch along the road to the Monte Verde Preserve. The venter of this specimen's abdomen is a startling light green and the rest of the body is mottled in caramel-yellow and brown, producing a bark-like effect. There is some faint green in the archedictyon of the tegmina. The body is deep and about 3.4 cm long. Analysis was confined to the field tape. At 16 C the male repeated his four-part songs every 2-3 s; his song rate was about 5 in 10 s. This calling song has some of the same features as those of Lophaspis and Pterophylla: the human ear perceives a rapid sibilant 'kate-ee-she-did'. Each of the four sounds is seen on an oscillogram (Fig. 10) to be a pair of pulse trains. At higher temperatures it is likely that these pulse trains would be unre solvable. The song is notably lower in intensity and less raucous than that of L. hebardi. Both species sang intermingled along the path to the preserve, but C. deciduus was not heard in the preserve itself. The pulses are rapid-decay and are poorly separated in time. Since the field recording was made with audio-limited equipment, ultrasonic frequencies are still a possibility. The audio spectrum is low-Q and has two energy peaks, one near 13 kHz and the other near 16 kHz. There is no energy below 10 kHz.
