What month does cicada appear in the northern Gregorian calendar?

When beginning of autumn came, a leaf fell from the plane tree, and the fallen leaves woke cicadas. They gave a long cry: "Cicada". This is a rather critical origin. Twenty-four solar terms, seventy-two, beginning of autumn will have: "Autumn wind, white frost, chilling."

Cicada is also one of the 24 solar terms, called beginning of autumn. As for the beginning of autumn solar calendar on August 8, 2006, I'll call it when I know.
