I don\'t know where their range peters out. A few years ago I was camping at the
Breaks Interstate Park on the KY/VA border. It had pretty much been raining
from South Dakota on but it was a beautiful, still evening as I lay in my tent
watching the fireflies. Of course the storm came in around 3 AM and I got
drenched. Spent the next night in a motel in Bristol TN drying stuff out. All
the rain did wonders for the rhododendrons.

I knew it was bad when I met a box turtle walking down the trail at Frozen Head
TN looking for a dry spot.

I never really consider the effects of local climate on flora/fauna.
I figured New England was \"temperate\" -- summers not too hot, winters
not too cold. And, figured the things that couldn\'t live there were
because of the cold winters. (E.g., Grandpa grew *figs* in his yard,
but it required an extraordinary effort; here, most of my neighbors grow
them effortlessly!)

So, snakes/reptiles had limited appeal when they had to contend with
the cold winters. Ditto citrus, etc.

It was only after moving here that I realized there are tings that
*need* the cold -- or, can not tolerate the heat. Ditto elevation,
etc.

yeah, that ain\'t gonna happen! :> ]

I recall one of my early experiences, here. I was visiting
and looked down to see an artichoke at chest level. \"Hey,
that\'s an artichoke!\"

I\'d never considered how or where they grew -- as long as I
could buy them at the grocery store! Ditto pomegranates.
(everyone knows oranges grow on trees so no big deal, there)

My first encounter with an artichoke was at a business lunch in a
fancy restaurant, with a crab stuffed artichoke as a shared appetizer.

I just grabbed a leaf and tried to eat it, and it didn\'t want to be
et. The proper technique wasn\'t at all obvious.

We have a great farmers\' market nearby, with real farmers selling
their stuff. In their natural state, on their stems, some veggies are
very weird.

I wonder what the time profile, the waveform, is of a firefly flash.

That would be a fun science project.

That\'s cartoons of flash patterns, not waveforms.

I\'ve seen some waveforms that look like rounded pulses, but the
detector bandwidth wasn\'t clear.

The pulses won\'t be super sharp, because they don\'t really matter.
It\'s the rhythm that usually matters for getting an invitation from a
female firefly.

Well, the biology folk will generally chose an adequate bandwidth,
which they do over time by finding the best BW for SNR (even if they
never heard of SNR). Bio amps usually have a max-BW knob of some
kind, usually implemented with a variable capacitor of some kind. For
picking nerve pulses, it was very often a rotating-element variable
air capacitor, used to control capacitance cancellation level just
short of oscillation.
