内源性运动程序是蝗虫成虫羽化前和羽化期间执行特定任务的肌肉活动重复模式的基础。其中几个电机程序进行了说明。出现是由纵向节段性收缩波的作用引起的，这些收缩波沿着腹部向前通过，使动物向前运动，脱离旧的角质层。额外的运动程序有助于腿和口器的解脱。在第三阶段（Hughes，1980 a），涌现行为被组织成重复的单元，定义为发作。后胸神经节对同时活动的运动程序的表达进行计时，以便它们在一次回合内彼此之间具有确定的相位关系。每一回合在功能上可分为3个阶段，每个阶段对动物的出现有不同的贡献。第3阶段的发作期和持续时间都受感觉控制，与羽化的进展有关。
Endogenously-generated motor programs underlie the repetitive patterns of muscular activity that perform specific tasks prior to and during adult emergence in locusts. Several of these motor programs are described. Emergence is caused by the action of waves of longitudinal segmental contraction that pass anteriorly along the abdomen, working the animal forward out of its old cuticle. Additional motor programs assist in the extrication of the legs and mouthparts. During stage 3 (Hughes, 1980a) emergence behavior is organized into repeating units, defined as bouts. The metathoracic ganglion times the expression of concurrently-active motor programs so that they bear definite phase relationships one to another within a bout. Each bout is functionally divisible into 3 phases, each of which contributes differently to the emergence of the animal. Bout period and duration of stage 3 are both under sensory control in relation to the progress of emergence.
