Mid-May update

Dragonflies are in the air in increasing numbers now. The number of observers is also on the rise.

We are on pace with 2023 (which set new high records) for numbers and species. For 2024, there are over 3,000 observations, over 250 observers, over 70 species. The weather for the next 10 days is also favorable.

There are a number of new County Records and also some new Early Flight dates. It's challenging to keep up with everything when I want to be in the field!

We have three counties without 2024 observations - Crawford, Williams, and Wyandot. Any help there would be appreciated.

With 2024 numbers so far, six counties have met the 1,000 observation goal: Gallia, Harrison, Holmes, Huron, Morgan, and Wood. Fayette had a new County Record, which puts it at 60 species, meeting that target.

Early May

We've had a big jump in Odonata numbers over the last week.

April is officially our best survey April. Nearly 900 research grade observations, 30 species, 120+ contributors. There will be several new County Records and at least a couple new Early Flight dates.

Only 13 counties did not have observations reported. See the map below. 2024 counties are the darkest. We only have three ciunties now with no April records.

End of April

2023 had our most ever April observations (367), counties (46), and species (20).

So far for 2024, we now have the most observations (500+) and the most counties (50+ so far). Also, now, the most species (23). Still possible on Blue Dasher, Skimming Bluet, Red Saddlebags, and Lancet Clubtail - these have all April records in the last three years.

Our final April days include warm weather and and a weekend - both good signs for submissions.

April 20 Update

We're seeing increasing Odonata numbers, especially Apr 18 - where we had warm sunshine and lighter winds. Today (April 20) also appears to have been good, even though the temperature was low.

37 counties have observations so far this April, with first ever April reports from Belmont and Defiance Counties.

We're now at dozen species. As expected, Common Green Darner is a clear leader, followed by our Forktails. The Darners are flying in, same with the Saddlebags. The Forktails, Common Whitetail, Blue Corporal, and Baskettail are all emerging from our local wetlands.

There are two new County Records for Variegated Meadowhawk, in Scioto and Coshocton Counties. Variegated Meadowhawks are migrants for the south and west - brought to us on the recent storm fronts. They should be possible anywhere in the state.

Conference update - Registration for the Dragonfly Society of the Americas conference should be open soon. Watch for conference details on the Ohio Odonata Society web (https://www.ohioodonatasociety.org/news/2024-meeting-updates)

This from Dave McShaffrey: With any luck, registration will be up next Wednesday (April 24th) for the DSA meeting including the meeting registration, housing (dorms), t-shirts and workshops.

The call for abstracts has been extended to April 30. Information on proposal submission is at: https://mailchi.mp/fbb3b86d6af0/dsa-meeting-call-for-abstracts?

Apr 3 Update

We have had Common Green Darners in the state for a little over a week. 9 observations recorded in iNat from Greene, Montgomery, Hamilton, Franklin, Logan, and Champaign Counties.

Logan and Champaign were both counties with first-ever March observations. Yay.

The near term weather is a bit cool, but warmer days are coming. Check out the OOS website on species with early flight at


Many of you will be out with your cameras for the eclipse - keep an eye out as your waiting - maybe you'll see a dragonfly!

Note - along with my first Dragon of the year, there was also my first tick. It's not too early for protection and checking the usual places (hairline, crevices).

Mar 26 Update - Dragons have arrived

Here we go!

Mar 25 goes down as our first photos of Common Green Darner in Ohio. The day was warm with strong southern breeze.

iNat Observations include Montgomery, Hamilton, and Greene Counties. Yay.

Also, note iNat observations on Stream Cruiser, Blue Corporal, and Springtime Darner in Kentucky. These will soon begin to emerge in Ohio.

Check the Ohio Odonata Society web for details on and and flight for the species.

Mar 12 - Odonata Flying Soon

Newly emerged Common Green Darners (Anax junius) are being reported in southern states. Variegated Meadowhawks (Sympetrum corruptum) in good numbers now in Texas. The first Fragile Forktail (Ischnura posita) was recently reported in Tennessee. So it won't be long until we have adult Odonata in Ohio.

We're past our early Common Green Darner date, which was Mar 6. Today, Mar 12, is our early date on Variegated Meadowhawk. The early Ohio date on Fragile Forktail is Mar 20. Our other March flier is Swamp Darner (Epiaeschna heros), with an early date of Mar 29.

Other early flight dates can be reviewed on the Ohio Odonata Society web site at:

I would note that our 2023 early observations were on Apr 3&4 with Common Green Darners and Variegated Meadowhawks.

Also, current wind patterns look good for pushing Dragons from Texas.

Mar 7

This is the next step on thinking about our survey. Based on input, here is a new plot of observation and species data.

First individual days.

The dataset is all days from 2017-2023, Mar-Nov. 1,470 datapoints. The x axis is the number of observations on a day divided by the number of observers. The y axis is the percent of species recorded of the possible species maximum for the three distinct day periods for a month.

Relatively linear to start, up to about 8 observations/observer/day. This gets us half of the possible species.

Now a composite by calendar day. 246 datapoints - days with data summed across the 7 recent years.

Numbers are pretty scattered on the low end of observations, but close the gap at the upper right.
