The spiracles are bigger and more near dorsal line than all the others. Their trachea branches are taper and abundant and form short tracheoles. This gave the tufted form to the trachea, which appeared shrubby. The trachea branches that arranged in other segments gave them a tree-like look. They do not directly supply oxygen for tissues, but they suspend in the hemolymph and attach to the muscle of the heart, so that they can move in constant with the contraction of the heart muscle.②The 8th segment tracheal tufts have thinner cuticle and basal lamina than that of the other trachea, and have much pad cuticle, which is appropriate for them to move, and their basal lamina have small pores, which are favour of the permeation of gas.③Injecting the methylene blue into the larvae to label hemolymph, we observed that the hemolymph flow into the heart through the 8th segment tracheal tufts.④Normally these tracheal tufts have all kinds of hemocytes, which are abundant in the tufts. A large number of hemocytes released from tissues attach to the tufts by changing their structure when anoxic stress happen.

气管分支细短而丰富，形成气管簇，呈灌木丛状（其它各节气管则呈粗树干状分布），它不是直接给组织供氧，而是悬浮在血液中，与心肌相连接，随着心肌的收缩而不断运动；②气管簇的内膜及底膜都比其它各节的薄，且管壁内膜具有更多的适合运动的垫状表皮，底膜还有小孔结构，这有利于气体的通透；③向体内注射蓝色的亚甲基蓝标记血液发现，血液流动方向是经该气管簇后而流回心脏；④正常情况下，气管簇处有各种各样的血细胞聚集，当缺氧胁迫时有大量的血细胞从组织中释放出来，通过变形而紧贴气管簇，有利于气体的交换；⑤给体内注射无色的亚甲基蓝发现气管簇比其它各节更易变蓝，说明该处具有更高的获氧能力。

On the bough also has many black spinules, touches, the hand can think hurts very much, therefore I all do not dare to bump it.
