From the brains behind brains on, this is moment of um.

Answering the questions that make you go I'm Mark Sanchez.

I'm Mark Sanchez. I'm Mark Sanchez.

Okay, imagine you're in a beautiful garden.

There are colorful flowers everywhere, fragrant herbs, and lots of butterflies,

gently flapping their way from place to place. You managed to get very close to a

super cool black and red one and according to your nature guide, it's called a cinnabar moth.

But wait, a moth? It's not a butterfly? Hmm. This reminds me of a question we got from

Silas. My name is Silas from Fitzp Wisconsin, and my question is, what's the difference between

a butterfly and a mouse?

My name is Brian Brown, I'm curator of entomology here at the Natural History Museum in Los Angeles, and my job is to oversee

research and growth of the insect collection here.

Six million specimens from all over the world, you never run out of new things to find.

Well, to start with, in one sense,

there's really no difference between butterflies and moths.

They're both members of a group called the Lepidoptera

or the scaly winged insects, and we tend to think of the colourful

de-active ones as butterflies and the drab nocturnal ones as moths but there's exceptions to both those rules there There are drab butterflies and there are day active

colorful moths as well. But in reality they're both members of the same group and especially

to tell butterflies from moths the antennae are really important.

But, butterflies have antennae that have what we call a clubbed tip, that is they're long and

narrow and there's an expansion at the tip.
