A moth's antennae are often feathery, unlike the clubbed antennae of butterflies.

The longer version

Antenna shape reflects how each group gathers information. Many moths fly at night and lean heavily on smell, so plume-like antennae present a large surface covered in receptors, effectively holding a net into the wind to catch airborne molecules such as the pheromones released by potential mates.

Butterflies are mostly active in daylight and depend more on sight, carrying slender antennae ending in a small club that tucks out of the way. These are tendencies rather than rules, since some day-flying moths have plain antennae and several night-active kinds rely on different cues. Scent detection of this kind can stay sensitive even at very low concentration.
