Some night-flying moths, says Adams, migrate using the moon as a primary reference and calibrate that reference with their internal geomagnetic compass. On moonless nights they navigate solely with the geomagnetic compass. During the dry season of the west coast lowlands of Costa Rica, reports Adams, moths fly up into moister mountainous areas and back down to the dry, west coast during the rainy season. The migratory moth species, Helicoverpa armigera, is widespread in Australia. The moths are mainly active at night, when they feed on nectar, mate, and lay eggs.
Moths have direct control of where they fly only when foraging close to the ground.
Flying at altitude with winds generally much higher than their flight speeds, moths go with the wind. These moths migrate by the light of the moon to the Snowy Mountains in southern Australia and this year the bright lights of the stadiums drew them off course. I know that the Earth is revolving around the Sun at the speed of about 30 kilometers per second. I am wondering why we don't feel the speed. Earth, however, doesn't change its speed.
