A number of people have given us assistance and we would like to
mention them here.
Karl Legler, Josh Rose, Aaron Brees and Robert Geerts graciously allowed us to use their photos of species that are uncommon in New Jersey or which we
haven't photographed yet.
Ann Johnson, an NJOS member, a professional web designer and the
author of the Odonates of Iowa website, helped us with web structure
and did many of the tricky little code things herself. If you
enjoy the site, much of the functionality was put together by her
(and for free!); there is no way we could have done it ourselves.
The checklists and included
material are © 2003 Jim Bangma and Allen Barlow. Additional
material may be the property of others as designated. The
printable lists (PDFs) may be printed and distributed in their
entirety for personal use free of charge.
Neither us personally nor the NJ Odonata Survey accept any
responsibility for mistakes that may have crept in at any level.
But if you find an error, let us know and we will fix it and then
hurl accusations at each other.
Seriously, Allen has maintained the database and we regularly
check and recheck for error. But much of it had to be
manipulated to fit the constraints of a web site and it is possible
that errors may have crept in. The maps were all drawn from
the database and, while they have been checked at least once, they
may have errors. If you become aware of any
mistakes, please let the webmaster know. This is very much a
work in progress and we hope to gradually improve it and remove any
All of us at NJOS have had a hand in writing some parts of the narratives
and the species accounts. Range, distribution and ID
information is based on our interpretation of the available data.
We have tried to err on the side of caution when an item was in
question or in dispute. In many cases, we admit that we
simply don't know, or that nobody does. In these cases we are
more than willing to be proved wrong. While all of the data
and much of the information has been supplied by Allen Barlow, the
final editorial cuts are by Jim Bangma and errors in wording and
grammar and the like are his fault. (Of course, he'll never
admit it) In some places where opinion is presented, if it is the
opinion of the NJOS membership, it is credited as such.
Statements such as "the author feels" are attributable to Jim, and
his fault when they are wrong. In a few instances, NJOS
members may disagree; in these cases, both sides of the disagreement
are spelled out.
Where possible, photos are the work of NJOS members. Since
I own the web page, in most cases I have used, and prefer to use, my
own photos. When we don't have our own photos, we have used
those of others; there is a bit about the photographers below, click
We are looking for photos of those species we are missing, and would
gratefully review any submitted. Unfortunately, we are not in
a position to pay for photos.
We try to include dorsal and lateral shots of both sexes.
If several known variants occur, we try to show them. Our
standard photo is resized to a maximum of 400 by 400 pixels although
in the case of some critters, especially darners and emeralds, we
have gone with 250 x 500. This size is designed to take up
approximately 50% of an 800 x 600 monitor, big enough to show
pertinent characters but still allowing room for data. We may
have to rethink this as finer resolution screens become the
standard, but we are trying to design this for the majority of
users. Similarly, all photos are saved at a jpeg compression
ratio that gives a file size of about 40k. Since the vast
majority of users still have dial-up, we hope this allows enough detail while
providing reasonable download times.
Many of the photos are posed, many are not. We haven't
bothered to identify them as such since the primary purpose is
identification, and even in art, everybody messes with nature to
some degree. All of the odes, however, were alive when
photographed. Both digital pictures, slides and negatives have
been used, film is currently scanned in a Nikon Cool Scan 4000.
One or two pictures are from high resolution flatbed scans of
Photos are cropped in Adobe Photoshop and if necessary, minor
adjustments are made to the histogram and to overall brightness.
Occasionally, the sharpen filter is applied, never more than once.
In a few cases, backgrounds have been selectively blurred.
Efforts have been made to not alter the color balance more than is
unavoidable in normal processing. We have reviewed the photos
on a variety of monitors; they are too bright on some, too dark on
others, and just right on mine. If they all look hopelessly
dark, we suggest you start thinking about a monitor upgrade.
All the photos are marked with copyright information and remain
the property of the photographer. Our experience has been that
most ode photographers are extremely helpful and generous people.
We ask you to please respect intellectual property rights and not
divert these photos for illegal or unethical use. If you do
need photos for some sort of project, feel free to contact the photo
owner or the webmaster, in most cases, higher resolution versions
We want to acknowledge the work of those people who have
contributed photographs to NJOS, usually in exchange for good will.
Out of respect for them and spam prevention, we are not including
email addresses, but if you need to contact one of them, drop us a
note, and we'll pass it on. The following people are listed is
alphabetical order, but "Friends of NJOS" are first, members last.
Aaron Brees: A budding young ornithologist or a bird bum,
depending on whether you talk to his Mom or his Dad. In his
first 2 weeks watching odes, Aaron added two new species to the Iowa
Karl Legler: co-author of Color Guide to Common Dragonflies of
Wisconsin, which, within its geographic scope, is one of the finest
ID guides out there. Karl is currently working on a new
addition and we are eagerly waiting for it.
Josh Rose: a rare combination of professional
ecologist and enthusiastic nature nut, Josh is trying to convert us
to the music of Akire Bubar and the Asylum Street Spankers.
They're growing on me, Josh, now if you would just appreciate Warren
Zevon. Josh has a cool website with photographs, links, and
some of his interests at http://www.duke.edu/~jsr6/.
Steve Walter: Great photographs, thanks, Steve! (We are
still negotiating what nasty things we can say, but check out more
of Steve's work at http://www.hmana.org/mulberry/.)
Robert Geerts, owner of Dragonflies
of Germany, graciously offered the use of his Black Meadowhawk
Allen Barlow: If NJOS had officers, Allen would be president.
Last fall he decided to dabble in bug photography. If this is
Sheryl Chacon: NJOS member and Passaic County expert, you have to
be in the field with her to believe. The lady catches skimmers
in her bare hands, walks logs across streams and usually ends up
dirtier than I do, but with more bugs.
Ann Johnson: Iowa bug guruette, author of
www.iowaodes.com and NJOS
member, Ann surfaces in NJ for a couple days every now and then and
now has a NJ list longer than her Iowa list.
Oh, and I took the bad ones.
Thanks, and please enjoy the website,
Allen Barlow, Jim Bangma and the rest of the NJOS crew
