Color variation in butterflies/moths
I've noticed that in many butterfly and moth species, there is a lot of variation in the colors of the butterflies/moths (and their caterpillars sometimes). I was wondering if the food that the caterpillars eat affect the color that they will be (and the butterflies/moths they turn into later)?
One excellent example is the promethea moth. In the first photo you'll see, it has a reddish pink color to it. In the second one, however, it looks almost black. Also, I claim no ownership of these photos. I'm merely posting links to them as a reference.
