NC State Parks and Natural Heritage Program's Butterflies of North Carolina by Harry LeGrand and Tom Howard -- best source of NC butterfly info available! For an annually updated online book, click on the left-hand link to the "Approximation". This is the source of much of the information I present on each species page.)
Will Cook's Site with lots of info about NC (and elsewhere) birds, butterflies, plants, and much more. Will has significantly helped me put together my web pages.
Giff Beaton's Site is one of the best for dragonfly and damselfly ID and has lots on birds and herps, too.
