Heading into the Last Week of August

As we pass Labor Day, Ode numbers begin to decline. Species diversity also begins to drop - and fairly quickly. So, get your Ode days while you can!

Numbers - We're heading for 30,000 research grade observations - probably by month-end. This still trails 2022 a bit in both observations and species. 2023 now has 133 species recorded. Over 1,000 people have submitted Odonata observations for Ohio. Reported numbers as of 8/22/2023.

Franklin and Ashtabula Co's are clear leaders on number of observations. Montgomery has the most species. Lucas, Franklin, and Summit Co's have observations from over 100 days. Summit, Franklin, and Cuyahoga Co's all have 90+ different observers.

On the low end, Allen, Paulding, and Wood Co's have the fewest number of observations. Paulding has the fewest species. Monroe, Mercer, Marion, Auglaize, Putnam, and Paulding all have fewer than 5 days of attention. Paulding, Mercer, and Auglaize Co's have only a single observer - that is apparently me.

Everything else is somewhere in the middle.

Eastern Forktail continues to maintain a lead over Eastern Pondhawk. 6 sp (Eastern Forktail, Eastern Pondhawk, Eastern Amberwing, Widow Skimmer, Blue Dasher, Fragile Forktail) have been observed in all 88 counties (the 7th - Common Whitetail - will hopefully turn up). Common Whitetail and Ebony Jewelwing are once again the species reported by the most people - relatively numerous and showy. The Forktails (Eastern and Fragile) have been seen the most days.

Thanks, I always enjoy the statistics. Very interesting. Might be interesting to separate the fliers from the perchers. The fliers are such a challenge to photograph. Dragonfly fliers like the common green darners, black saddlebags, and prince baskettails are very common statewide, but very hard to document. Out of the 1,000+ observers, I would guess less than 50 observers have at least one research grade observations of all three. Probably no observers have at least one observation of all three in every county they visited (assuming 5 or more counties visited).
