Doug,
Thanks for doing this. It will be fun and informative watching this map get
more and more colorful. Great job!

Per the suggestion of Steve Stedman and Larry McDaniel, here is a map showing
the status of BAMONA moth documentation in each of the counties of Tennessee.
This first version isn't very useful, though, because of my choice for category
ranges.

Choosing the category ranges was a dilemma. This first version of the moth map
is scaled to be roughly equivalent to the (revised) butterfly map. That is, it
displays the same number of categories and the same colors, with the scale
proportioned so that the maximum* category represents the same idea as the
butterfly map: meaning something like "virtually complete documentation except
for strays."
Unfortunately, the resulting map is useful only for establishing a baseline
against which future iterations of the map can be compared, since the moth
documentation effort in Tennessee is much less complete than the butterflying
effort. Only the two bottom categories are actually displayed; subjectively,
they mean "no documentation" and "very incomplete documentation."
This situation will change soon. When BAMONA catches up with Larry's efforts,
at least one county will be pushing up close to the 400-species category. I
expect that others will follow shortly.

* Charles V. Covell, Jr. (1999) lists 2388 taxa in The Butterflies and Moths
(Lepidoptera) of Kentucky, and states that there might be another 300-400
species beyond that. I'm assuming that Tennessee and Kentucky will have
similar statewide totals: ~2600 species.
