Things have went surprisingly well, most of the missing were accounted for
without increasing the death toll only slightly.
A lot of cleanup has been accomplished, not any rebuilding yet but it
will happen soon.
It seems that every able bodied person in the state has contributed in
some way to the relief of those affected, a local radio station chain
pretty much turned over the airwaves to connecting the haves with the
have nots, it is the way America is supposed to work.

Same here, SWMBO has a masters in Anthropolgy and Biology,
I've seen every nature show available to mankind.
The Cicadas annoy a lot of people, but they are music to my ears,
reminds one of the drones on a bagpipe.
The birds love em, the first few billion out of the ground
probably get eaten.

Sound incredible. The 13 year cycle is interesting. Not that many birds do
that.
I remember my youth near a swamp/pond/wetlands when the bullfrogs would roar
all night long. One frog doesn't make that much noise. But multiply it by
a thousand or so, the noise levels get right up there.
Now are things going in your neck of the woods after the recent storm
activity?

I always enjoy the cicadas, be they 7, 13 or 17 year ones. To me, they
epitomize summer. I also feel sorry for them, singing away about their own
death...just imagine, all that time in the ground and such a short time to
enjoy renewing their cycle of life.

Interesting, where I grew up they are on a 17 year cycle.
The first year, living in a house my parents built in the middle of a
woods, was introduced to the 17 year Cicadas, my parents called them
locusts.
That was 1948.

DO:
I would guess the pleasure was denied me. My visits
stretched a week at a time over 3 years using IU
as a convention center. For a person used to
humidity being close as the ocean, the difference
in atmospheres was memorable, including the nights
of cricket a capella.
The only other mass encounter to mention with the
bugs was in the vast basin off of the transverse San Emigdio
range in California where we felt a days-long rush
of cricket hordes. The snap-crackle-pop sound from
necessarily driving over them was neither music nor
advertisement to the ears.

We have those as well, it just that these particular ones
are 13 yr.
They are a smaller bug than the 17 yr.

Heh!
What's a hoot is to watch a cat confront his first cicada. The cat will
worry it for a while, then the bug will go opossum.
Almost always, the cat will pick up the insect to carry it god-knows-where
for further processing.
The cicada will begin to buzz.
Cat invariable leans back and spits the bug twenty-five feet!

Now that I live in the northwest the two things I miss from Louisville
are the bullfrogs and the lightning bugs :-).

Different species. The ones called "periodic cicadas" are either
13 year broods or 17 year broods, with neither overlapping.
The every-summer cicadas are actually 3 year cicadas, but there are
3 broods overlapping.

I hate that usage, but gave up the argument years ago. My first
exposure was the first full summer in Virginia (having moved in the
previous August). I was 12 and they freaked me out. Something
about the bulging red eyes.
Now I like them, though we are just outside (~10-20 miles) of the
brood range for this end of Ohio. We had our emergence a few years
ago. The annual ones are the song of the summer.

I've seem fireflies in the mid Willamette Valley. Not the hordes we had in
NW Ohio, but at least some. Salem has red squirrels, which are common east
of the Mississippi, but not so common out here.
I don't miss that one damn cricket in the basement that would start up just

General thought is that it avoids preditors getting adapted to them.
Cicadas aren't agile and they aren't stealthy. So it helps that
nothing is used to eating them on a regular basis.
Now why those *specific* time spans, I have no clue.
And I'll correct myself. It seems the 13 and 17 year broods *are*
the same species. Just different populations.

Because they're prime numbers. A predator that's around every year will catch
them only every 13 (or 17) years; a predator that's around every other year
will catch them only every 26 (or 34) years; a predator that's around every 3
years will catch them only every 39 (or 51) years; and so on. It makes it
*much* more difficult for a predator to co-evolve a synchronous hatching
period: suppose they appeared every 12 years instead of every 13 -- then
they'd be vulnerable, potentially, to predators that hatched every 12, 6, 4,
3, 2, or 1 years.

I'd say shells came first. According to Wikipedia: The Fibonacci
sequence is named after Leonardo of Pisa, who was known as Fibonacci.
Fibonacci's 1202 book Liber Abaci introduced the sequence to Western
European mathematics.
It sounds familiar, but, since you brought it up, How are shells related
to the Fibonacci sequence? It surprises me that all shells would have
this commonality. I would have expected the kind of variance that you
see in the growth rings of trees.

Answering my own question (by copying from Wikipedia):
It is sometimes stated that nautilus shells get wider in the pattern of
a golden spiral, and hence are related to both Ï and the Fibonacci
series. In truth, nautilus shells (and many mollusc shells) exhibit
logarithmic spiral growth, but at an angle distinctly different from
that of the golden spiral.

Um, y'all have this slightly backward.
It isn't that nature knows advanced math. It is that advanced math
is what it takes for humans to describe nature. Fibonacci didn't
define a sequence just to amuse college freshmen. He did it to
make sense of the way that plants tend to be formed -- one stem,
two leaf groupings, three leaf groupings, five petals, eight petals,
etc..
Maybe there's a Great Mathematician drawing on the chalkboard.
Maybe there's mathematical structure making us imagine a chalkboard.
Ether way, it is pretty amazing how things tend to fit/work together.

Wow, that makes sense!

Part of me wants to say "GO, MOM,GO!"
Part of me wants to wish condolences.

Best wishes on you, either way.

I've heard other such reports from other areas but nothing here past some
crickets chirping and the odd frog. I remember there was a pretty big hatch
three years ago in the Cincinatti area.

Are they still around up there, or have they been wiped out due to
pollution/insecticides?

I have been know to have a chirping cricket in the house wake me, which
caused me to get up, locate the cricket, find a pry bar and hammer, and
remove the piece of baseboard he was hiding behind.

LM:
There's an informed volcano girl on sci.geology.
There is also a large contingent of trolls whom make
the group pleasant, if sometimes unfortunately
sparse, reading once they are blocked.. But your wife
might enjoy the highlights.
If your wife has not seen the Scablands presentation
that PBS did, get her a copy; quite the intelligible and
dramatic presentation. As always without first-hand
observation, there's room for some difference in
explanation but the effort was very workmanlike
by my conception.
Perhaps there's an audio of your cicadian chorus
on the web. I've found fossils in the California
asphalt deposits but they didn't talk back much.
A few summer stays around Bloomington introduced
my ears to the tidal play of crickets. If that pales
against the surging of your current performers, it
must be something.

No way ... the dog has canine epilepsy, which makes him susceptible to
having seizures. He takes Phenobarbitol twice daily to control them
and is on a very specialized diet as recommended by his vet. You can
second guess the vet's advice all day long, but I'm not changing a thing
on this end.
