    The usefulness of this site is dependent upon the submission of new county records and good photos. All records are reviewed prior to being added to our data. When possible attaching a photo to your new record will make it much easier to accept a new record. Good photos that will help the reader understand different color forms, sexes, and ages are always welcome although the webmaster reserves the right to manage the photos. Please contact us first if you are unsure of the suitablility of your photo.

  • Westfall's Snaketail photo by Ann JohnsonNews

    Iowa odesters have been busy since this website was last updated.  New species added to the state list are: Springtime Darner (Basiaeschna janata), Pale Snaketail (Ophiogomphus severus), Westfall's Snaketail (Ophiogomphus westfalli), Stream Cruiser (Didymops transversa), Banded Pennant (Celithemmis fasciata), Blue Corporal (Ladonna deplanata), Golden-winged Skimmer (Libellula auripennis), and Painted Skimmer (Libellula semifasciata).


    Perhaps the most exciting discovery has been of a snaketail along the Boone River.  It has been identified as Westfall's Snaketail (Ophiogomphus westfalli) which until now was found only in the Ozarks of Missouri and Arkansas.  More research is needed to determine if this is indeed a disjunct population in very different habitat or if it is only similar.
