Passive flight

Definition

A mode of flight where an insect relies primarily on wind currents or other external forces to achieve flight, rather than actively flapping its wings.

Etymology

From Latin 'passivus' meaning 'inactive' and 'flight', from Old English 'flyht'.

Example

Many dragonflies utilize passive flight techniques to conserve energy during soaring.
