Calling all Ode Enthusiastists.

The next Odolympics starts on 14 January 2023!


The Dragonfly Society of the Americas, Sociedad de Odonatología Latinoamericana and Odonata Central are partnering to conduct the Odolympics 2023.


  • Odonate survey of the entire Western Hemisphere
  • Everyone can participate by entering observations into Odonata Central or iNaturalist
  • July and December Survey dates to accommodate participants in the entire Western Hemisphere
  • The goal is to record as many species from as many places as possible
  • You can have fun and contribute to citizen science by helping to create a snapshot of odonate distribution


Everyone can participate. The goal is to try to record as many species from as many places in the Western Hemisphere as possible in the two census periods to generate a snapshot of odonate distribution.

Dates: 14-22 January 2023.

The final repository for the data will be Odonata Central. These data will be critical in filling gaps in the Odonata Central data set. All data on Odonata Central are freely available to everyone to explore or download.

Help make this project a success. Plan to participate.

How to Contribute

Overview: Submit your odonate observations to Odonata Central or join the iNaturalist projects. Enter observations on as many days of the Odolympics as you wish.

All Odolympics participants must be registered users of Odonata Central, even if you plan to join the iNaturalist projects. Registration is free and takes only a few minutes.

If you are planning to join the iNaturalist projects, you have to register on Odonata Central and add your iNatualist user name to your profile. (After registering and/or logging in, click the blue My Account button in the top menu.) If you do not do this, your iNatualist observations cannot be counted toward the Odolympics total. This only has to be done once for all future Odolympics projects.

There are three ways you can enter observations for the Odolympics

Options 1 and 2 are for users of Odonata Central. Option 3 is really only for people who only use iNatualist.

  1. Directly into Odonata Central. We encourage participants to enter data directly into Odonata Central. Odonata Central accepts complete checklists of photographed, collected and observed only records for any location and tracks abundance data.
  2. Imported into Odonata Central from iNaturalist. This is the preferred way to get iNaturalist observations into Odonata Central. You can enter observations into iNaturalist and then import them into your Odonata Central account by cutting and pasting the URL of the iNaturalist record. This copies location, date, species, and photographs into Odonata Central so they don’t need to be entered again. This way you can also create complete checklists (including Observed Only records) and assign records to your stored OC location names. See this video tutorial. NOTE: If you use this method, DO NOT JOIN one of the iNatualist Odolympics projects as you will duplicate records when the iNatualist project records are imported. You can always use this option outside the dates for the Odolympics.
  3. Joining the iNaturalist Projects. If you prefer to just use iNaturalist alone, you can join the project called Odolympics July 2022. Observations reported to iNaturalist by project members during the Odolympics will be automatically collected into these projects. To avoid duplication, do not import these records yourself into Odonata Central using option 2.

How to make sure your observations are counted in the Odolympics totals

  1. If using Method 1 or 2 above. On the first screen of Add Records in Odonata Central, be sure to select Odolympics from the drop down list as the project for each checklist you enter. The Odolympics project is only available in the drop down list AFTER you enter a date of observation that falls during the Odolympics.
  2. If using Method 3. Be sure you are a registered user of Odonata Central and have provided your iNaturalist user name in your Odonata Central account.


At any time, users can view the Odolympics data in Odonata Central by opening the filters and setting the Project filter to “Odolympics” for records, species lists or maps. Records contributed to iNaturalist can be viewed by visiting the Odolympics iNaturalist Project. After the iNatualist data are imported into Odonata Central, the aggregate data can be viewed there.
