Why and how are insects attracted to night lights

Post by LookDeepr »

I am at the very beginning of my macro journey, and in my readings so far the "moth screen" has come up as a preferred way to attract (and photograph) night insects. But even before this, having seen how night insects buzz around any sufficiently intense light, I have often asked myself, WHY? This question was even more pressing to me considering that in some cases the fly-by was at their peril.

This is where the article in the link below proposes an answer. Quick read, and fascinating. There is also a video to go with the story. I hope you will enjoy it and it will shed new light (pun intended) on your night time macro stacking ...

It is nice to see empirical research on this mysterious subject, and their explanation is novel and interesting. I have my doubts though. My own kitchen window attracts moths, wasps, and rhinoceros beetles at night. The rhinoceros beetles in particular repeatedly crash head-on into the window, and moths also often flutter or hover (in the case of sphinx moths) against the window head-first, continuously pushing forward towards the light. And many insects land on the window and stay there, with their backs facing the darkness.
