Why Do Some Moths Have Feathery Antennae?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do some moths have feathery antennae?

The Big Idea

Male moths often have feathery antennae to catch scents in the air! The tiny branches give the antenna lots of surface for catching scent molecules. It works like a net for smells.

Feathery Branches

Step one: spread the branches. Each antenna has many tiny branches on both sides, so it looks like a little feather. More surface means more places to catch scent molecules.

Catch a Scent

Step two: catch the scent. A female moth gives off a special scent that drifts through the air. The male's feathery antennae catch it, even when it's a very faint trace.

Follow the Trail

Step three: follow it. The male moth flies back and forth, following the scent to its source. He can sense it from far away, even when only a few scent specks reach him.

A Closer Look

Let's take a closer look! The antennae look like little feathers. Each one has lots of tiny branches. They catch scent specks like a net. The moth follows the scent to its source.

Quick Facts

Quick facts! Moths have a great sense of smell, and many of them fly at night, when it is dark. Moth antennae can have thousands of tiny scent sensors. Butterflies usually have thin, club-tipped antennae instead. Watch moths near a porch light from a distance, and don't catch them.

Think Like a Scientist

Now, think like a scientist! Draw a moth's antenna as a feather with lots of branches. Then draw a straight stick antenna. Which one would catch more scent specks drifting by? Count the catch points on each.
