Light micrograph of the plumose antenna of an unidentified male mosquito. The antennae of the females are less feathery. Those of the male are precisely tuned to detect the female wingbeat tone. Resonant oscillations are picked up by an organ (Johnston's organ) at the base of the antennae. This elicits in the male the sequence of actions necessary for mating. Magnification: x22.5 at 35mm size.
