Why are noctournal insects attracted to light? It seems to me that
evolutionary selection of this trait would be potentially harmful. Over
the millions of years required for this behavior pattern to emerge, the
only possible light source I can envision that would have been present
consistantly would be fire. Why would it be advantageous to be attracted
to potential immolation? Any insight from you entomologists?
