Abstract: The behaviors of Teleogryllus emma (Ohmachi and Matsumura, 1951) were reported and the characteristics of their songs were analyzed. The behaviors included feeding, cleaning, avoiding, mating and singing. The songs contained calling song (CS), courtship song (CtS) and rival song (RS). The results of time domain characteristics showed that the songs contained dominant tone and subordinate tone. both CS and CtS included two kinds of tones, while the subordinate tone of CtS is longer than the one of CS. RS contained only the dominant tone. The results of frequency domain characteristics analysis showed that the frequency of rival song was higher than the ones of CS and CtS.
