Iowa Odonata Survey

The Iowa Odonata Survey is patterned after a similar "organization" in New Jersey; i.e., little structure, no meetings, no dues. All you need to do to become a member is submit your information.  Our purpose is to maintain good data on the occurrence of odonates in our state, educate folks on the bugs that inhabit many of their favorite nooks and crannies, and provide consultation to the state's conservation organizations on the critical habitats and environmental indicators as they relate to the odonata.  Water quality is such a major issue in Iowa environmental concerns and odonates provide us with some great information on the quality of our watersheds.

Meet the Founding Members

Cruden & Gode's work, PDF The Odonata of Iowa, was published in The Bulletin of American Odonatology, Vol. 6, No. 2.  Much of the data you will find here was derived from their manuscript.

Bob Cruden

Bob is a botanist by trade and a professor at the University of Iowa.  He is a former director of the Lakeside Lab at Lake Okoboji.  His project of collecting and cataloging the odes of Iowa, a project that extended over several years, has made Iowa one of the best known states in the nation.

O.J. "Bud" Gode

Bud Gode Bud was the other half of the Cruden & Gode team and responsible for the many dot maps of county records for our state.  These records have given us a baseline for future work.  After retiring in Arizona, he passed away on 1 May 2005. His impact on our current knowledge is immeasurable.

Steve Hummel

Steve HummelSteve is our "data coordinator" and has been studying and collecting odonates since his college days at the University of Northern Iowa (longer than he probably wants to admit!).  He maintains an extensive personal database of records as well as a significant collection of voucher specimens.  Steve is our northern Iowa expert since most of his time is spent north of Interstate 80.  He is very active in the Dragonfly Society of the Americas having recently served as its president.

Ann Johnson

Ann Johnson AJ is a birder gone bad as she now spends summers chasing bugs.  She is our "web geek" who built the first Iowa Dragonflies and Damselflies web site back in 1999 after becoming frustrated with trying to learn about these critters through random web searches.  Her personal records are primarily from locations near her home in south central Iowa. In 2009 she authored Dragonflies and Damselflies in Your Pocket: A Guide to the Odonates of the Upper Midwest (a Burr Oak guide).

Aaron Brees

Aaron Brees Aaron is a former bird bum/unemployed naturalist turned attorney for the Iowa Department of Natural Resources. He became interested in odes one summer and promptly began adding new state records near his parents' home in southern Iowa. The combination of his natural history and legal backgrounds bring a special skill set to growing our knowledge of Iowa's odonates.




Jim Bangma

Jim Bangma Jim, New Jersey's "web geek", not only gives us an out-of-state perspective but his sense of humor helps keep other things in perspective as well.  Many of the photos on this site, some taken in Iowa and others from New Jersey, are courtesy of Jim.  He made a major discovery in the odonatology of Iowa while sitting at the computer reviewing my photos of baskettails, thereby instigating the addition of Epitheca costalis to the state list. Jim is a co-author of Field Guide to Dragonflies and Damselflies of New Jersey.

Friends of IOS

A special thanks to Jim Durbin for the entry of Cruden & Gode's records into our database and for supplying a number of his photos.

While our intent is to complete an Iowa photographic collection, we have relied on a number of people to temporarily fill in the blanks. We are grateful to the following people for their willingness to share their work:

  • Allen Barlow
  • Sheryl Chacon
  • Doug Danforth
  • Robert Geerts
  • Karl Legler
  • Pete Moulton
  • Dennis Paulson
  • Keith Turrill

Much remains to be known about the distribution of a number of species and to some extent which species live here. If you can add to this knowledge, you may use the form on this web.
