I grew up in a place where these were common.Are you kidding, I love these things.
A creature, a bug, that sleeps for 17 years and then burrows out of the ground on the same day or within a day or two of a billion of its fellows, climbs a tree, escapes it's shell and then does nothing but sing and screw until it lays eggs and dies. They fascinate the hell out of me.
In this part of the country they come in several varieties. These are some that come every year, a wave that come every 6 years, and the big wave that comes every 17 years. Some parts of the country also have a 13 year cycle.I grew up in a place where these were common.
They are as big as my thumb, very docile, and when they sing it's LOUD! They used to make such a racket all night when they emerged every few years.
There must have been more than one wave of them, because it was definitely not 17 years between. Some of them came out every year, pretty much.
