Essentially an annotated checklist of North Carolina insects. Since this state has such a variety of habitats, from the fir forests and mountain balds, to the sub-tropical coastal areas, this book is a useful resource for much of the eastern US. There are no illustrations, but some comments on life history, phenology, and regional occurence in that state. Supplements published later, are hard to find. The work is incredibly comprehensive, at over 500 pages and 10,000 species in the original edition. There was a fourth supplement covering hymenoptera in 1995, which should be available in libraries.
Information on date of collection (phenology) is particularly valuable, and given for most species. There are the occasional valuable comments on life history. Taxonomy is often out of date, but one can usually figure out the recent nomenclature. I'm not sure this work will ever
be surpassed in its comprehensive nature.
