Moths Use “Wireless?"

Because scientists have found that though they place a- female moth in a wooden pillbox, soundproof and scentproof, the male moth always will find its mate, they have been led to believe that moths faake use of a system similar to wireless telegraphy. A Vapoorer moth In a sound-proof box will attract the male of its species from all directions. It has been proved that the males are attracted neither by' sound nor scents The London Dally Mail says that if experiments were conducted it undoubtedly would be shown that elec-tro-magnetic waves of a very short length are used, as both glow worms and fireflies emit light under similar conditions, and that it is not Improbable that other Insects use longer and invisible waves. Moths have antennae, which, besides acting as feelers, may be employed as transmitting and receiving aerials. The antennae of the female, who 18 the transmitter, differ in design from those of the male, who receives. When the male alights he swings his antennae much as an operator swings a wireless directionfinding frame to find out from what directions signals come.
