Like a moth to a flame.

This phrase really, really intrigues me. Something that drives you, pushes you, calls you to itself. And then you stop existing. That dazzling light guides you. You circle it endlessly. You wish to make it yours. Only in the end, you are consumed by your own desires. You cease to exist and become a part of something else. You know it's fatal but yet you can't stop. You choose to get consumed. Its something disastrously beautiful - well, in theory at least. It feels like literature. It feels human.

Here is the scientific reason why it happens. If you open the source link, you'll find some other alternative theories refuting it and giving other explanations. But here -

"Around the world, moths make kamikaze dives into light bulbs and open flames with such regularity that they have their own idiom. What is it about lights that make moths so crazy?

For a long time, scientists blamed the moon. Moths used the moon as a navigational beacon, it was argued, keeping it at a constant angle to their direction of travel in order to fly straight. Light sources used by humans, whether they’re campfires or porch lights, threw a monkey wrench into this system. The moon is far enough away that the angle between it and a traveling moth isn’t going to change much, even after the moth flies a great distance. With a closer light source, though, the angle changes considerably after only a short distance. A moth confusing a light bulb or candle flame for the moon, the hypothesis went, would notice this change and attempt to correct its path by turning toward the light. After just a few course corrections, the moth would set itself into a tightening death spiral towards the light and eventually crash into it, either going down in flames or thwacking its poor little head."
