And upon observing a mass of insects swarming around my porch light in Sedona I felt compelled to research why it is they flock to light in the darkness. A quick google search reveled a tragically beautiful metaphor:
They mistake it for the sun or the moon. It is their instinct to head towards the light in the sky, and their vision and mental processing skills are not all that great. So they think a lightbulb is the way out. It isn't so much that they love the light, just that they are getting mixed signals and don't know how to resolve that. They think the light is the sun, but they cannot go anywhere once they reach it, and they keep trying, often to the point of killing themselves from the heat.
