Butterflies and moths have been separated in most languages for a long time indeed. Scientifically however the two groups do not exist. Yet even scientists continue to use the distinction. So we will be happily using it on these pages as well. There are two main differences between butterflies and moths. Moths have a connection between the front wing and the hind wing, which butterflies lack. Butterflies therefor can manipulate the two wings separately. Furthermore all butterflies have rather long, threadlike antennae ending in a knob. Moths have all kinds of antennae, but never threads ending in a knob. Sometimes other differences are mentioned, but usually these do not exist. Most butterflies do fly during daytime, but some fly during the night as well. And some moths fly in broad daylight only, like the clearwings
