Bug Flights At Night
This photo shows insects flitting about a lamp of the Abbey in Tihany, Hungary. This 10-second exposure captures dozens of insects (many are moths) drawn to the light on this mid-summer's night. Numerous night flying insects evidently use bright lights for orientation purposes. Attempting to keep a constant angle to a light source, they move closer to the light each time they change position. Away from cities, the moon serves a similar function and allows the bugs to buzz off once they're comfortable with their orientation. It should be noted that insects can be killed when they fly into the hot lamp, may die from exhaustion from spending an entire night flying around it, or may be gobbled up by predators that take advantage of their predicament.
