There was a lot of ways to slice and count the data, but it looks like Neotibicen tibicen is our 2023 annual cicada winner.

Is there a chance another annual or proto-periodical cicada is more plentiful in North America? Yes of course, but in areas where people are using the iNaturalist app most frequently, which is likely not isolated or out of the way areas, Neotibicen tibicen was most plentiful. Millions of uncounted Platypedia putnami emerging around every odd and inaccessible stream in the west, maybe,

Methodology:
1) Downloaded Research Grade data from the 2023 North American Annual Cicadas project.
2) Combined sub-species with species counts. In other words, I totaled Neotibicen tibicen + Neotibicen tibicen tibicen + Neotibicen tibicen australis to get Neotibicen tibicen.
3) The 1 species per user + location column reduces the number by one species per user per location. In other words, if I submitted 50 Neotibicen tibicens in Edison, New Jersey, it only counts as 1 (one).

Swamp Cicadas (Neotibicen tibicen) seem to do well everywhere that isn't too cold or too dry. They do well in city parks as well as groves of trees in rural farmlands. So, they'll probably "win" because they're findable in high population areas. "Swamp" is a bad name from a diagnostic perspective, as they are not limited to Swamps.

Northern Dog Day cicadas will likely overtake Resh this week.

IDing the "green group" can be vexing without location, and photos top, bottom and side.
There's likely a lot of N. canicularis, linnei, pruinosus, winnemanna and robinsonianus with wrong IDs on this site.

Exuvia (molts, skins, shells) remain difficult to ID.
Location helps.
Dark coloring on the wing bud is a good indicator for N. tibicen.
Dark rings on N. hieroglyphica.
Etc.

At this moment the Superb and Swamp Cicadas are neck & neck. I think Swamp cicadas will come out on top.

Top cicadas week ending 5/20:

1) Quesada gigas, #2) Megatibicen resh, and #3) Neocicada hieroglyphica.
