Why moths fly to light?
Surely everyone who saw a warm summer night around the fire goes the dance of all sorts of bugs, wondered: why they do it? After all, night insects are on the night to fly in the dark. If they were so loved the light, then would fly in the afternoon. Paradox of nature.
In fact, there is no paradox. Light attracts not only moths, that is, insects from the detachment of scales. Birds are also discouraged by huge flocks near the beacons during seasonal migrations. Fish float. So, Sair is catching up with networks, luring it there with powerful spotlights. Yes, and among insects, not only moths are susceptible to. Representatives of almost all detachments with a variety of lifestyle fly to him. Mostly twilight and night forms, but often around the lantern and typical day days.
Love for the Light Here, and the reasons forcing the moth fly on a bright and hot lamp or straight into the flame of a fire, two.
So, the daily moth could get a lot from the bulbs back from the evening, and at night, someone disturbed him or he was awakened by bright light. Waking up from sleep, the moth reveals himself surrounded by darkness, which he perceives as a closed room. The light, as the famous ethomologist George Mazochin-Porshnyakov rightly notes, is a universal open space indicator. So the frightened insect rushes to the light spot, as to the saving way out.

Other business – Night forms. Throughout the millions of years, they used the moon for orientation in space. It is noticed that, if you quickly move in a straight line, landscapes around and flashed, and the moon moves as if parallel. This happens because the distance to it compared to the overcome person or, as in this case, the insect is huge and the direction to it almost does not change. This is what makes the moon with an excellent guideline: moving at a certain angle to the night luminaire, the selected direction is preserved.
With the advent of artificial light sources, everything became more complicated. The tested navigation method began to give failures. "Capturing" the burning light bulb in the field of view, which went to the night journey of the Moth continues to hold the direction of its flight at a certain angle. If this corner is direct, the insect begins to describe a closed circle around the light bulb. If the angle is stupid, the moth is removed from the light source on the spiral. And here are the poor women who chose a sharp angle will approach the lamp, too, spirals until it encounter.
