Why do insects fly away from light bulbs?

Light bulbs appear brighter and radiate their light in multiple directions. Once an insect flies close enough to a light bulb, it attempts to navigate by way of the artificial light, rather than the moon. Since the light bulb radiates light on all sides, the insect simply cannot keep the light source at a constant angle, as it does with the moon.
