The corn earworm moth, Heliothis zea (Boddie), emits a 10-μm infrared signal which is chopped by the wings. The oscilloscope recordings demonstrate that the signal has an azimuth and a glide path vector. A burning candle randomly mimics the vectored infrared output of the corn earworm and other moths. The output of the moth is related to the peculiar affinity of a moth for a candle flame. It is postulated that the vectored infrared signal may serve as a homing device between the sexes. It is believed that a candle flame is a confusing mimic to the moth signal and that the infrared from the flame triggers the “candle flame” behavior of the moth. There are picket-fence sensors (coeloconica) on the antennae which may be infrared detectors for the signal.
