[doep] Daily (intermittent) Open-Ended Puzzle: Why do moths fly the way they do?

My understanding (possibly bogus) is that moths spiral into flames because evolution has designed them to fly in straight lines by noting celestial lights. When the light is nearby, keeping its position fixed in their visual space causes them to spiral inward toward it.

Fine. But why is it an evolutionary advantage for moths to fly in a straight line? Where are they trying to get to so quickly? And isn’t there a metaphor for MBAs somewhere in here?
