A marvelous（了不起的） lesson appeared for me just now as I was exiting through the garage.  

 

As I opened the garage door, I startled a large moth, which, upon spreading its wings, displayed a bright red "tail" hidden by the motley（杂色的） brown wings, more a "butterfly" than a moth（蛾）. 

 

It flew immediately to its perceived escape, the circle-topped window where it frantically tried to exit thru the invisible wall of closed glass. 

 

I raised the third-car garage door in hopes of aiding its escape. That caused it to fly higher and higher and become entangled in a spider web. Fearful that it would remain entangled in the web, I selected a long-handled broom to assist him escaping the tangled threads. 

 

At this, he returned to furiously pumping his wings and banging into the glass, which was, in his perspective, the pathway of escape, but remained his cage.
