In view of recent queries I am reposting the following from 2/26/99.
Since the only butterflies flying here are Mourning Cloaks and Cabbage
Whites (which I can identify), I have NOT yet tried the book under fire.

===================================================================
Since the interchange last week, several people have asked me for more
details on the new book by Jeff Glassberg which I had seen briefly two
weeks ago. Now that my copy is in hand I feel more confident in
commenting on the book. Firstly, a disclaimer. I am favorably inclined
towards the approach used in this book. In writing our book on
Butterflies of New Jersey, Joanna and I made the decision NOT to include
anything on identification, since Glassberg's original book BUTTERFLIES
THROUGH BINOCULARS (Boston to Washington DC) so adequately covered our
area for a remarkably low price. At the same time Pyle's AUDUBON guide
was available and the new Opler FIELD GUIDE was published, so we felt
we were hardly justified trying to make another field guide.
That said, I turned with anticipation to the new volume which is
likewise published by Oxford University Press (New York) with a list
price of $18.95. (ISBN 0-19-510668-7) A friend purchased my copy for
under $14 from one of the internet sites.
There is some general introductory material aimed at the novice
butterfly watcher (or butterflier).
Each species account is cross-referenced to a color Plate and includes
the general size (using some common species as references), brief notes
on identification, habitat, abundance, brief information on hosts, and
some general comments on status. There is also a phenogram which
includes the relative abundance for Wisconsin, New York, North Carolina
and Louisiana. Critical field marks are highlighted in bold face.
[Others will have to interpolate].
There are 71 color plates featuring the 629 plus photos of which
Glassberg took 591. Each plate has a size reference, and all of the
photos on a given plate are to the same scale.
I am no color expert, but I think that the color reproduction (at least
in my copy) is very true as well as attractive. For each species Males
and female are shown where different, and both ventral and dorsal views
are shown. Whereas many of the older guides showed the dorsal views of
butterflies such as blues and hairstreaks, one seldom sees these views
in life, so the photos in this book are particularly valuable for field
identification.
There will inevitably be some controversies regarding the ability to
identify certain species in the field. The Confused Cloudywing
(Thorybes confusis) probably requires genital dissection to be sure of
the identification. I have heard the same claim made for the Hickory
Hairstreak (Satyrium caryaeovrum), but I have photos of individuals
which clear match the requisite field marks for this species which is
rare in central New Jersey.
Glassberg provides field marks for distinguishing the Appalachian Brown
(Satyrodes appalachia) from the Eyed Brown (S. eurydice). I must
confess that I have had trouble applying these in the field, and it
worries me when I find two Browns---one apparently of each species---at
a location. But there are certainly many other examples of butterfly
systematics which will benefit from more detailed field work.
Harry Pavulaan mentioned to me that there are two misidentified photos
among the Azures (but I can't find his email at this moment).
I was particularly impressed by the excellent photographic
representation of so many of the Grass Skippers (Hesperidae) with dorsal
views of male and female and at least one ventral view shown. This is
marked advantage in identifying these difficult creatures, although one
should heed the warning that worn individuals should often be left
unidentified.
Although I consider myself Cosmopolitan, it too me a while to realize
that I must be a Yankee, since I was puzzled by the selection of Gulf
Fritillary for the cover---a beautiful Gulf Fritillary---I might add.
The book follows the North American Butterfly Association checklist of
Common names, which is a major effort in standardizing such names. I
think it's a great idea, although the idea of having a "Northern
Southern Hairstreak" leaves me cold. I did not agree with the name
chosen for this species.
There are several production features that were mildly annoying.
1) The type face is grey (as is evident when one looks at the boldface
text).
2) The critical text facing the illustrations is in a small type face,
obviously intended for novices under age 40. For most of the plates
the lower half of the facing pages is blank.
3) Finally, I really liked the more regional (Boston-Washington) range,
whereas this covers the entire eastern U.S. including eastern North
Dakota down to eastern Texas, which is both a strength and a weakness.
[The publisher obviously wanted a bigger marked for a single volume, but
this is a disservice to the field user who usually has some idea what
part of the country they are in. ]
On the other hand having the range maps, small as they are, facing the
plates, allows one to quickly include or discard a species that one is
trying to identify.
So in conclusion, this is a new book with a template similar to the
original volume, but with mostly new illustrations and new text. It is
a steal, even at the list price.
