What's the Difference Between a Butterfly & a Moth?
by Kendra Norrell, Assistant Butterfly Curator, Lewis Ginter Botanical Garden
In case you didn’t know, this week is National Moth Week. Here at the Butterflies LIVE! exhibit, we are known for having a variety of butterflies, but periodically we will get some moths to liven up the exhibit with their nocturnal glory. Having the moths in the exhibit, sometimes, brings up the question: What makes a moth different than a butterfly? There are the easily known observations: moths are more active at night and typically are a duller color than butterflies. But there are other things that create a difference as well.
One of the main differences between moths and butterflies is how they reach their adult stage. Both go through a metamorphosis from the pupae stage, but what they’re in differs. Butterfly caterpillars become a chrysalis as their pupae stage. Moths, on the other hand, make a cocoon. What’s the difference, you might ask. Well, moth caterpillars spin their cocoons out of silk thread that comes from within. While a caterpillar’s chrysalis is located under the last layer of skin which they shed and a chrysalis comes out.
In the exhibit, we have both butterfly (Monarch butterfly) and moth (Luna moth) caterpillars. Hopefully, while they are in the exhibit, we will be able to see the different transformations to the pupae stage!
