THINK YOU KNOW ME? WHO I AM?

In my youth i've crawled 

Amongst runners branches and leaves 

With gusts winds i sometimes fall

Or captured and bereaved 

Slowly as night turns into day

My changes begins to show

In a completely different way

I'll be faster where i go

I'm always in your gardens 

Most times neglectively

Very colorful and weight lighten 

You even try catching me

You're marveled at my beauty 

I make your children smile 

If you think that you know me

Then tell me who am i ?
