Feb 26 - days and numbers

Still thinking about survey and the number of observations to represent species. A different look is to start with individual days and plot number of species against number of observations on those individual days. Using recent years data (2021-2023), for our busier months (Apr-Sep), this is 524 days. There is data for every day for all three year in Jun-Sep, some missing days in Apr-May. Here's the chart:

The dots are color coded: Blue is Apr-May, Green is Jun-Jul, Orange is Aug-Sep. Remember that this is the same number of days (183) for Jun-Jul and Aug-Sep. Slightly less for Apr-May (158).

As expected, Jun-Jul show the highest numbers. Good diversity on the wing and people looking.

Apr-May is clustered on the lower left. While not much to see early on, there are some higher numbers in late May.

Aug-Sep is clustered generally higher than Apr-May, but well below Jun-Jul. No days above 50 species, even with higher numbers of observations.

Feb 23 - getting ready

Days are increasing in length. Spring flowers are off to an early start. Maybe a dragon soon? We're only a couple weeks away from our earliest Common Green Darner observation (March 6).

This got me thinking on what and when. As noted, CGD gets us started, then followed by Variegated Meadowhawk, Fragile Forktail, and Swamp Darner as possibilities in March. Check out the early flight date chart at https://www.ohioodonatasociety.org/species-flight-range-by-early-date

I updated the chart on observations and species count for our season intervals. This is based on all the data.

The peak for both occur in the last 10 days of June - the scales here are adjusted to match the peaks. Interesting that our species count generally outpaces our observations in this charting. I think it holds that the more observations we make, the more species we will see, but there's some wiggle room here. Things ramp up quickly starting in late April, then species hold on a little better in late September.

February 13

In review, 2023 had some interesting day numbers - which led to thinking more generally about the season and the data.

The number that started it was 721. This is the number of observations identified to species on 7/14/2023. This is the highest one data total (ever) in the data, ahead of the 696 from 6/25/2022. We also had a good day on 6/17/2023 with 693 observations. These "days" have more records than most historical "years", and any year prior to 1959 (which had 1014 observations).

We had three days in 2023 with observations in 40 different counties: 6/25; 7/14; and 7/16. High county days for earlier years were a peak of 44 counties on 7/8/2019, and three days for 42 counties: 6/21/2019; 7/14/2019; and 6/19/2022. We have to go back to 6/11/2016 to find the highest county number prior to the recent survey years (2017-2023) - this day had 17 counties and ranks as #659.

The 2023 day with the most observers was 7/16 with 75 different users. This is behind earlier year highs of 86 observers on 6/12/2021 and 80 on 7/13/2019.

One of the most remarkable numbers for 2023 was 75 species recorded on 6/4. 6/3/2023 was close with 68 species. These two days combined had 84 users recording 1012 observations covering 81 species. These species counts (75, 68, 81) represent half or more of the annual species totals.

Blue Dasher had the high one day observations on 7/14/2023 with 76. This number trails Eastern Forktail on 5/29/2022 with 112, and Eastern Pondhawk on 8/13/2022 with 103.

Widow Skimmer had the most counties in a day for 2023 with 21 on 7/14. Earlier highs are Blue Dasher in 2019 with 25 counties on 7/13 and 24 counties on 7/14.

Widow Skimmer on 7/14/2023 was also the high for number of observers for a species in a day with 27. This also lags the Blue Dasher on 7/13/2019 where 35 people recorded observations.

For individual users on individual days:
monicap273 recorded 229 observations on 6/3/2023
lisaclairemiller recorded 55 Blue Dashers on 8/8/2023
jimlem recorded 34 species on 7/27/2023

Five days had users with observations in 5 counties:
6/21/2023 - monicap273 (Hancock, Huron, Lorain, Sandusky, Seneca)
6/25/2023 - monicap273 (Columbiana, Harrison, Holmes, Jefferson, Tuscarawas)
6/26/2023 - dmcshaffrey (Carroll, Guernsey, Noble, Stark, Washington)
9/3/2023 - jimlem (Allen, Defiance, Logan, Paulding, Van Wert)
9/20/2023 - jimlem (Auglaize, Champaign, Mercer, Shelby Van Wert)

Early February

Following up on a post from a year ago: 'How are we doing with our survey effort?' From the data, let's look again at the combinations of county and species. With the 2023 data, we have 6,806 combinations of the 88 Ohio counties and the possible species. This number grows as County Records are established. We can compare this cumulative number to individual years, or now that we have 7 years of survey data, a multi-year accumulation. The chart shows the most recent years. In orange is cumulative co|sp value - as theoretical maximum growing year by year (scale is on the left). The blue line is the 1 year % value (right scale) of the max. The green line is the percent of the theoretical max accounted for in the 7 year running accumulation (scale is on the right). Note that prior to the start of the statewide survey, the percent yearly observed was in single digits, even with 7 year data, the % was only in the 20% range.. We are now over 80% - meaning a significant majority of the documented co|sp pairs are being recorded. This helps answer the question - we are doing better, and overall, pretty good.

Comparing pre-1950 data to Survey II (2017-2023), Survey II had 4129 Co|Sp combinations not recorded through 1950. Pre-1950 had 473 not in Survey II. What stands out as missing?

By species.
Rainbow Bluet in 21 Counties.
Lyre-tipped Spreadwing in 20 Counties.
Ruby Meadowhawk in 18 Counties.
White-faced Meadowhawk 14 Counties.

A partial explanation could be habitat loss through various means. Ruby Meadowhawk just needs more/better photos.

By County.
Ashland Co is short 37 species.
Defiance, 27 species.
Erie, 27 species.
Ottawa, 25 species.
Paulding, 35 species.
Williams, 33 species.

All of these deficits are probably due to decreased attention. These would be opportunities.

Jan 15 - A New Ohio Odonata Society Web Site

The Ohio Odonata Society has a new web site.

The url is www.ohioodonatasociety.org

This is OOS’ 3rd generation of an online presence, the 1st was at Marietta College, the 2nd was at u.osu.

Many hours of discussion and tech-work have gone into this new web site, primarily by OOS volunteers Jay Heiser and Jim Lemon.

The new web site has much of the County and Species reporting that for the last few years was distributed in the Dragon Flyer Newsletter. The newsletters are also archived on the site.

As with all websites, there is still work to be done, and you can help. We are especially interested in County-level descriptions of local wetlands. Please take a look, especially at Coshocton (where Jay has a wetland property) as an example.

Let us know what you think. Any mistakes are ours - we will correct as needed. Also comment on ideas you might like to see.

jimlem and jheiser

Jan 5 - 2023 County Numbers

I cut off 2023 data for reporting on 1/1/2024. You have to draw a line somewhere. So these numbers are already out of date. Submissions arriving since 1/1 will be incorporated in the survey database, just not right now.

Here's the data by County.

The # denotes where the 2023 value is above the 5 year average
The + denotes where the 2023 is a new all-time high value
The [brackets] indicate top value in the column

The numbers are good - we are doing a better job of survey. These numbers should probably -not- be interpreted that Odonata numbers are increasing.

Hello 2024

The 2023 Ohio Odonata data set is in place - at least for the moment! We will welcome past seasons data in 2024, but they won't be represented in the Ohio Odonata database until we do 2024 processing.

That said, here are some 2023 numbers. 38,539 observations for 2023, 135 species, all 88 Counties represented. 38,539 sets a new yearly high.

There were 133 new County Records, with Four-spotted Skimmer leading by a wide margin with 23 new Counties. We have 11 new early flight dates, 13 new late flight dates. We increased the flight period of Red Saddlebags by 10 days on the early side (TC in Clark Co). We extended Elusive Clubtail flight by an amazing 23 days (DT in Hamilton Co).

Monthly totals included 6 months with new high observation numbers:

Apr 367 (new high)
May 4,246 (May 2022 had 4,250)
Jun 11,384 (Jun 2022 had 11,813)
Jul 11,264 (new high)
Aug 6,229 (Aug 2019 had 7,637)
Sep 3,624 (new high)
Oct 1,135 (new high)
Nov 290 (new high)

County and Species numbers coming soon!

Update - Happy Solstice

Holiday Greetings - We've had a little snow and cooler temperatures. I see ice on the ponds, but no doubt, Dragon nymphs under the ice, Damsel eggs sequestered in plant material.

There are a few 2023 (and earlier) observations still arriving, but the numbers grow slowly at this point in the season. New maps and other reports are being worked on.

The January Dragon-Flyer newsletter is out. If you didn't receive it or would like to see a copy, message me (jimlem in iNat, jlem@woh.rr.com for email).

Also keep in mind the Ohio Odonata Society is hosting the Dragonfly Society of the Americas meeting this summer in Marietta, Jun 28-30. Watch for details.

Be well, look forward to the coming Spring.
