Mid December Update

The year seems pretty much complete. Submissions to the project are a trickle. I will be reporting numbers and try to keep things correct if new data arrives.

For the year, we have had 26,232 Observations, comprising 140 Species, from 1,071 Observers. Every Ohio county is represented in the data. These totals are good on observation and observer numbers, but short of the record years 2018 and 2019. 140 species is the most we've ever recorded in a year.

We had 110 New County Records, covering 58 species, in 54 counties, from 48 Observers. Again good numbers but short of high marks in 2018 and 2019.

The most observed species (over 1,000).
Eastern Pondhawk 1,733
Blue Dasher 1,707
Common Whitetail 1,465
Fragile Forktail 1,385
Eastern Forktail 1,383
Widow Skimmer 1,378
Autumn Meadowhawk 1,155
Eastern Amberwing 1,038

No real surprises here. These are common species at a variety of wetland habitats. It's interesting that Fragile Forktail had more observations than Eastern Forktail for the second year in a row - that's never happened before. Our 2021 Eastern Forktail numbers were considerably below the trend from the Ohio Odonata Society database.

Counties with Most Observations (over 1,000).
Ashtabula 1,982
Lucas 1,948
Franklin 1,903
Stark 1,468
Coshocton 1,138
Summit 1,049
Montgomery 1,022

Again no surprises given the previous monthly reports. Most of the counties got a big lift from individual observers (more on that to come). No substitute for local people getting dragon-fever, both quantitatively and qualitatively.

Counties with Most Species (over 70).
Geauga 78
Lucas 77
Montgomery 73
Stark 72
Lake 71

Great and varied habitat + core of dedicated observers = lots of species.

Counties with Most Observers (over 70).
Franklin 137
Summit 110
Hamilton 93
Cuyahoga 90

Terrific to see counties with around 100 observers.

Species in the Most Counties (over 75).
Blue Dasher 88
Eastern Forktail 88
Eastern Pondhawk 88
Fragile Forktail 88
Widow Skimmer 88
Eastern Amberwing 86
Common Whitetail 84

Pond Skimmers and Forktails, consistent at many wetlands.

Species with Most Observers (over 200).
Common Whitetail 332
Ebony Jewelwing 271
Widow Skimmer 271
Eastern Pondhawk 249
Blue Dasher 245

This is fun - Whitetail and Jewelwing have the most people reporting these species. Eye-catchers for sure.

More to come...

For context, the entire 1989-2002 survey and resulting book had about 27K records, so great job folks!
