Where does the phrase "autumn insects under the window whispering" come from?

From:

"Autumn Insects"

Bai Juyi

Under the dark window, there is a humming sound in the deep grass.

My heart misses my wife in autumn, and my ears feel sad on rainy nights.

Interpretation: Hiding secretly under the dark window, hiding gently in the deep grass, thinking about what others are thinking in autumn, and fearing to disturb others on rainy nights.
