Insects are known to approach light sources. I know that they use it as navigation tools, by maintaining a constant angle between their path and the light beam. However, if a light source is exceedingly bright, I mean like "blinding" bright, would an insect still use that as navigation tool?
What I have been thinking is, the insect wouldn't use it, and try to escape from the light source. I believe this because the extreme blindness may cause the insect to damage it's eyes, although I am neither knowledgeable nor capable of confirming this.
Such a thing usually doesn't happen in nature, so I'm unsure if such a test has been made before. Nontheless any help would be great. I also understand that my definition of "bright" isn't well defined, since I don't know the maximum intensity an insect can handle. I also haven't mentioned the insect, so for consistency sake, assume it to be a Black Witch moth (Ascalapha odorata)
Would an insect use a light source that's exceedingly bright to navigate?
