There are also plenty of annual cicadas in North America, which I assume you are talking about NA with the 13 and 17 year brood cycles. While not nearly as loud as the broods, annual cicadas have always been a sure sign of the seasons. I have always considered the end of summer when the cicadas stop singing. They become such a constant background noise that it is easy to forget that they are even there if you have lived in the area for awhile.
