haltere; balancer

Japanese: 平均棍 - へいきんこん(英語表記)haltere; balancer
haltere; balancer
A club-shaped mobile body on the thorax of dipterous insects such as flies and mosquitoes. It is a degenerate hind wing that vibrates together with the forewings during flight. It also moves independently when stationary. It is thought to be a balancing organ that senses the rotation of the body axis, and there is also a theory that it is a kind of tympanic organ related to flight motion. It is said that if the haltere is removed, flight becomes extremely unstable. In twisted-wing insects, the forewings are modified into halteres, which are also called pseudohalteres.

ハエやカなど双翅類の昆虫の胸部にある棍棒状の可動体。後翅が退化したもので,飛翔の際前翅とともに振動する。また静止中に独立して動く。体軸の回転に感じる平衡器官と考えられているほか,飛翔運動に関係する一種の鼓膜器官であるという説がある。平均棍を取除くと,飛翔が著しく不安定になるという。ネジレバネ (撚翅) 類の昆虫では前翅が平均棍に変形しているが,これは偽平均棍とも呼ばれる。
