[birdky] RPT: Periodic cicadas ... a few leftovers ? ? ?

During the past three days, I have heard periodic cicadas four times in areas 
where they were present last year:
 
1) our family farm in eastern Jefferson County (a single individual)
 
2) in Frankfort (a single individual)
 
3) on a BBS route in rural Lee County this morning (a single individual)
 
and
 
4) at the Rock Bridge Picnic Area parking lot, where Ben & Mary Yandell, Eddie 
Huber, Matt Stickel, and myself heard what actually sounded like a little 
chorus of the "phaoroh" type about 1030 this morning.
 
I've already forgotten all of their names, but the calls that I've heard are 
the same as the ones I heard at these locations last year.
 
One must assume that out of the millions of insects that emerged "on time" in 
2008 that there are a few laggers in the class ? ? ? With all that we humans 
have done to the environment, I wonder if we might be messing with the 
synchrony of the emergences ... or maybe there have always been a few that had 
their timing off, thus leading over centuries to the various broods ? ? ? All 
very interesting ...
