I haven't done a range map for this site yet. I hope to work on it in the next month or two. You might have been thinking about BugGuide's range map. I built those, but I can't use the same method for this site since I'm handling the locations differently (and this site is not just US/Canada).
I also have a test script in the works to output KML for use in Google Earth, but it needs some more work before I make it available.
Mike, didn't there used to be a range map....or am I just missing it ?
