Happy Equinox

Another September, another passing of the seasons.

Additional observations are coming in for September and some for earlier months, and for some earlier years! Data points have utility, even when it complicates keeping track!

September is currently over 2,400 research grade observations. Good. At this point only 1,000 behind 2019, which is nearly the same amount we are behind 2019 on the year. 2022 now around 31,500. It appears we're in for some cooler temperatures, but Odes will fly with sunshine. Don't stop looking.

Many species will have their best year ever for 2022. A few species that are already past their previous peak year: Common Whitetail, Eastern Amberwing, Ebony Jewelwing, Violet Dancer, Blue-tipped Dancer, Slaty Skimmer, Orange Bluet, Black Saddlebags, Painted Skimmer, and Great Blue Skimmer.

Looking for some additional county observations. These counties have fewer than 100 observations:

less than 90:

less than 80:

September - 10 days in...

A little bit of clouds and rain today, but we did pretty well in the first 10 days of September. There have been some reports of darner-swarms as they move south. So, there's that.

Ocellated Darners had several observations (Geauga Co), joining Elusive Clubtails (Hamilton Co) as additional species for the year - now at 135. We also had some additional reports on Red Saddlebags (Coshocton Co) - so come on Striped Saddlebags and Variegated Meadowhawk!

Thanks to rasamoto (9/1) and monicap273 (9/9) for the Pike Co Eastern Amberwing submissions - these observations make Eastern Amberwing our sixth County-Complete species. Previously we had Fragile Forktail, Widow Skimmer, Blue Dasher, Common Whitetail, and Eastern Pondhawk as County-Complete. Just now we got Eastern Forktail | Scioto Co from monicap273! This makes only the fifth observation for Eastern Forktail in Scioto Co..

August is close to 5,400 new research grade observations. We're over 8,700 RG for July, and already at 1,300+ for August. Getting close to 31,000 observations for the year, the record is 32,570 from 2019 - I think we're in range if the weather holds up.

September Update

September can have some great days to be out! Clear skies and moderate temps make it good for me. Ode numbers diminishing, but some cool things still in flight. Look for Mosaic Darners, and for migrating swarms of Common Green Darner and Black Saddlebags.

Elusive Clubtails have been sighted, bringing the species list to 134 on the year. Still hoping for Ocellated Darner, Striped Saddlebags, Variegated Meadowhawk.

Also looking for a couple things to add to the County Complete list: Eastern Forktail in Scioto Co and Eastern Amberwing in Pike Co.

August has over 5,000 new research grade observations. This number will increase a bit as people get things submitted. We're over 8,500 RG for July, and over 11,000 for June.

Stark and Franklin Co's have the most observations so far with over 2,000 observations. Lucas Co is close as well. Counties on the low end are Ross and Van Wert Co's, both with fewer than 50 submissions.

Montgomery has 75 species so far. Guernsey, Van Wert, and Knox are all below 20 species.

Good efforts, thanks everyone.

August 2/3rds +

Now over 27,000 research grade observations for 2022. With the arrival of Smoky Rubyspot and Green-striped Darner we're at 133 species for the year. Looking for Elusive Clubtail, Ocellated Darner, Striped Saddlebags, Variegated Meadowhawk. These four sp would put us at 137. The 141 for 2020 is probably out of reach unless we have some extraordinary good luck.

There are still observations coming in for earlier in the year. We are well above previous high numbers for May (4,067) and Jun (10,980). Jul numbers still below 2019 - but climbing.

Eastern Pondhawk numbers are rising quickly, sights set on taking over top spot from Blue Dasher. We should soon see a spike in the number of Autumn Meadowhawk reported. We're on track compared to recent years, with more to come - Autumn Meadowhawk recently being the top-reported species in Sep, Oct, and Nov.

Thanks to recent submissions from monicap273, we now have a number of species reported for all 88 Ohio Counties in 2022: Fragile Forktail, Widow Skimmer, Blue Dasher, Common Whitetail, and Eastern Pondhawk.

Still looking for a these two species for County Complete:

Eastern Forktail: Scioto
Eastern Amberwing: Pike

Nothing else is close. Next in line would be Ebony Jewelwing, but this is down the line with eleven counties needed, and we are at the tail end of the their season.

With recent new County Records, we're at 105 for the year. Skimmers dominate the new County Records - Painted and Great Blue with 7 each, Spangled with 5, Slaty with 4, Golden-winged with 2. Columbiana and Ottawa Co's each have 6.

Mid-August Update

Cooling evenings and shorter days, some species numbers seem to be trending down. But we have late summer species picking up!

It's been a couple weeks since we've had a report on Painted Skimmer, so they may be one of the species that are done. The historical late date for Painted is Aug 9. For 2022 we have 278 observations. This nearly double the previous high of 143 in 2019 and is one of the stand out species for the year.

Another species with good numbers is Ebony Jewelwing - and it's not done yet. Our latest observation for Ebony is Sep 26. We have 1,008 observations at this point. The previous high is 1015 in 2019. We should be able to push past that number.

Altogether, there are 27 species that will have their most observations in a year. Ten or so additional species could end the season with highest ever numbers.

County Complete!

Fragile Forktail is now recorded in all 88 Ohio counties! Thanks to monicap273 for the two Aug 12 observations.

Widow Skimmer is now complete (8/16). I’ll post the observations for Van Wert and Paulding later this week.

Who's next?

Species: Needed Counties
Blue Dasher: Wyandot
Common Whitetail: Morgan
Eastern Forktail: Athens, Scioto
Eastern Pondhawk: Knox, Wyandot
Eastern Amberwing: Knox, Pike, Wyandot

600 Observation Goals met!

With the research grade observations for 2022, all counties that were targeted to get to 600 observations have reached the goal. Thanks to everyone that contributed.

60 Species Goals still out there.

Progress on the goal of getting all counties to 60 species is taking more time. Counties with the most need are Noble and Van Wert. They each need 10. Belmont (8), Seneca (7), and Brown (7) are next in line.

August Update - 8/9

July was another good month for Ohio Dragonfly Survey.


For July 2022, we are around 7,800 Research Grade observations from 457 Observers covering 99 species in 81 counties. This number will still climb a bit as people clear up their backlog.

For all of 2022 we have over 24,000 RG observations from 840+ Observers in all 88 counties. Pretty good pace, in line with recent years.

We have a total of 131 species so far in 2022. 13 counties reporting 50 or more species.

Previous year: # Species recorded
2017: 127
2018: 135
2019: 139
2020: 141
2021: 140

So we're ahead of 2017, on par with 2018. we'll need some luck to match 2019-2021.

We have 102 new county records for 2022. This is comparable to last year.

Previous year: # County Records
2017: 174
2018: 326
2019: 319
2020: 114
2021: 111

Blue Dasher (1,841) is easily the most reported, although Eastern Pondhawk reports are closing quickly.

Ebony Jewelwing (273) and Common Whitetail (261) have the most users reporting.

Franklin (1,917) and Stark (1,750) are the clear leaders on number of observations/county.

Franklin (97) and Summit (90) counties have the most iNat contributors.

Montgomery has the most species at 74. Lucas follows with 71.

County Complete

We're getting close on several species to having them reported in all 88 Ohio counties in 2022.

Species: Needed Counties
Blue Dasher: Wyandot
Fragile Forktail: Adams
Common Whitetail: Gallia, Morgan, Paulding
Widow Skimmer: Paulding, Union, Van Wert
Eastern Pondhawk: Knox, Paulding, Wyandot
Eastern Forktail: Adams, Athens, Gallia, Scioto
Eastern Amberwing: Knox, Paulding, Pike, Van Wert, Wyandot


We started the season with some target Counties based on recorded observations and species. We wanted every county to get enough new observations so their OOS total was 600 or more observations and 60 or more species.

We needed 118 new county records over 20 counties, so far we have 25 CR in 13 counties. Only 2 counties have been taken off (Harrison and Preble). A few counties are still possible (Fayette, Huron, Lawrence, Monroe). Note that historically the likelihood of new county records goes down considerably after July.

We needed 2,598 observations over 23 counties, so far we have 3,727 in 23 counties. Happy to report we are down to 1 county that still needs observations (Meigs). The others (Belmont, Brown, Carroll, Columbiana, Fulton, Guernsey, Hardin, Harrison, Henry, Holmes, Huron, Jefferson, Lawrence, Marion, Monroe, Mercer, Morrow, Noble, Perry, Putnam, Seneca, Van Wert) have enough new observations to meet the 600 goal. Nicely done.

July 13 - Update on Goals

In March we looked at the original survey goals (success!) and new goals for 2022. We're now at a mid-point in this year's season, so how are we doing?

Here are revised maps for our goal of every county having 1) a minimum of 600 observations, and 2) a minimum of 60 species. As expected, it's easier to log observations than it is to get new species. But we have 23 new county records in 12 of our target counties.

Here is the observation map. Counties in lighter gray (13) are where we have met the target. Blue counties (10) still need work. 4 could be finished with one good day (Brown, Hardin, Monroe, Putnam). The others will take a bigger effort (Belmont, Fulton, Henry, Meigs, Noble, Seneca). But I think all of these are "in the zone". Note - I’m updating the maps as we go along - Brown, Hardin, Henry, Putnam Co's now exceeding the goal.

Here is the species map. We cleared Harrison and Preble counties (but they had the lowest requirements). Closest to the new goal would be Fayette (2), Huron (2), Lawrence (2), Monroe (2). The others will probably still be goals for 2023.

7/7 - 2022 County-Complete

Completing Species/County datasets

The Ohio Odonata Society maintains data for Ohio species by county and date. In 2018, we recorded Blue Dasher observations in every Ohio county, this was a first. Blue Dasher was our only 'county-complete' species in 2018. It was a fun thing. We promoted the idea in 2019, and had 7 species: Blue Dasher again, Common Whitetail, Eastern Amberwing, Eastern Forktail, Eastern Pondhawk, Fragile Forktail, and Widow Skimmer. It should not be a surprise that these are some of our most common species. With CoVid and everything in 2020, we did not have anything county-complete. 2021 had a recovery with 5 species recorded in all 88 counties.

And now we're starting the countdown for 2022. Species, followed by current county number, then needed counties. I'll add to the list as other species get closer (Widow Skimmer would be next, but only at 68 now, then another drop to Dancers).

Blue Dasher (86); Carroll, Wyandot
Fragile Forktail (84); Adams, Fulton, Morgan, Putnam
Common Whitetail (80); Allen, Fulton, Gallia, Morgan, Ottawa, Paulding, Putnam, Vinton
Eastern Forktail (78); Adams, Athens, Carroll, Columbiana, Gallia, Hocking, Lawrence, Scioto, Wayne, Wyandot
Eastern Pondhawk (78); Allen, Carroll, Fulton, Gallia, Holmes, Knox, Paulding, Seneca, Union, Wyandot

Happy Ode'ing

July 4 Update

So far for 2022: 15,000+ research grade observations; 122 species; all 88 counties; nearly 600 contributors. Jun 2022 was our biggest month ever in terms of submissions, at this point 9,990 RG observations. This could go over 10K as people finish up their data entry. Lots of interesting observations with new sites for "special" species and 70+ new county records. We also went over the 500-mark for members of the Dragonfly Survey project on iNat. Busy, busy.

Eastern Forktail has the most observations for the moment, Blue Dasher is rising quickly. Blue Dasher also has the most counties with 86, only Carroll and Wyandot have not yet reported a Blue Dasher. Fragile Forktail is next with 84 counties.

Franklin Co has the most observations - over 1,200. 5 counties have fewer than 20 reported observations: Gallia, Allen, Paulding, Van Wert, and Carroll.

Following an earlier trend, we continue to see many Painted Skimmers, now with 7 new County Records. Great Blue Skimmer is also being reported in many areas - also with 7 new County Records.
