Insect physiology: The mouthparts of moths and butterflies breathe through strategically positioned micropores

Insects employ a tracheal system to transport oxygen and carbon dioxide to and from the body’s cells. A new study discovers a micropore-based mechanism of respiration in the coiling mouthparts of moths and butterflies, which allowed these insects to evolve intricately long mouthparts without also ev...

Description
Summary:Insects employ a tracheal system to transport oxygen and carbon dioxide to and from the body’s cells. A new study discovers a micropore-based mechanism of respiration in the coiling mouthparts of moths and butterflies, which allowed these insects to evolve intricately long mouthparts without also evolving proportionally larger body sizes.
