Look at these beautiful moths!
I prefer moths over butterflies. There is a delicate subtle beauty to them, like they belong more in nature than butterflies do... I think I feel that way because their colors are more nature colored and their habits seem more reasonable for nature -- quite unlike butterflies with their daytime gallivanting, irreverently flashing around their unnatural hues!
Moths also beat out butterflies in the cuddle-factor department. Their modified scales give them a cute furry apperance... just look at them! They're almost like flying hamsters! Last I checked, hamsters are generally more cuddly than arthropods (which I love too! Just not for cuddling.)
