Butterfly and transverse orientation

Dear Dr Seow,

Wonder whether butterfly exhibit transverse orientation like moths? Or it is simply attracted by the ultra UV light wave of lamps? Cos a Spotted Sawtooth came into my apartment after 12 of the night and orbiting around the lamp.

Thanks~

I have really no idea about that.
Since moths & butterflies evolved together they probably do.
Many crepuscular butterflies are attracted to light, eg. Common Evening Brown & Palm King as well as Skippers.


TL Seow: Cheers.

Thanks Dr Seow~
