Abstract：This article mainly take the method of raising observation and capturing of camera to observe the basic behavior patterns of Deracantha onos Pallas such as research nymphal behavior, common behavior, acoustic behavior and mating behavior pattern for a brief description. It apply software for data analysis, from the angle of insect behavior to observe from nymph to adults. The results show that: Nymphs can not call, only in the afternoon there will be amount of feeding activity. Nymphal molt is related with temperature and diet. Adult in various environmental conditions all appear there will be clear tentacles, tentacles swing, moving and feeding and other behaviors but in the case of malnutrition and narrow space, the case of cannibalism occurred .To study on the sexual maturation of Deracantha onos Pallas calling under the cases of males alone, two males ,one male and one female, observing their behavior and recording the time of song in 24 hours. The longest time of calling is the case of male alone . The time of calling for 492.84min + 82.52min in a circadian time .The shortest time of calling for 239.85min + 40.55min in the case that have two males, and at night there will be no calling. Feeding an temperature also effect on calling time. Sound play an important role in species to communication , it also play a role in the mating patterns . When mating, females crawl to the male 's back, male tail was recurved ,female tail was bented, there is connected to the sexual reproduction hole, the mating behavior end up with female reproductive hole have hanged the spermatophores.
