antennae

The long feelers situated on the head and close to the eyes. They are however not tactile but used for detecting airborne scents and currents.

• In Papilionoidea the antennae end in bulging tips called clubs.
• In Hesperioidea they have hooked tips and the club is found just before the tip.
• In some Lycaenidae like the genus Liphyra the antenna tapers gradually.
