2023 North American Annual Cicadas Location Project on iNaturalist

Neotibicen tibicen aka Morning Cicada aka Swamp Cicada formerly Tibicen chloromera is the winner!!

August 11 Neotibicen (small)

Summary below and on iNaturalist.

As of December 31st, 2023

Neotibicen tibicen, aka the Swamp Cicada aka Morning cicada, is the 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.

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).

Cicada 1 species per user + location Species totals
Neotibicen tibicen 402 437
Neotibicen lyricen 193 201
Neotibicen superbus 188 263
Megatibicen resh 155 232
Neotibicen pruinosus 139 178
Neotibicen canicularis 125 134
Megatibicen grossus 76 81
Neocicada hieroglyphica 54 63
Neotibicen robinsonianus 47 51

Neotibicen linnei 34 36
Diceroprocta apache 28 35
Neotibicen winnemanna 23 26

Tibicen tibicen wins!

About the project

There are 3 types of cicada lifecycles:
1) Periodical: cicadas with a life cycle set to a specific number of years, with a predictable series of emergence years. Magicicada, for instance, emerges every 17 or 13 years depending on the species, and we have a calendar of years when and where they will emerge. Some “stragglers” do emerge each year.
2) Annual: cicadas that emerge every year without fail.
3) Proto-periodical: cicadas that emerge in small numbers every year (annual), but the size of the emergence varies significantly from year to year. Examples include Platypedia (see Platypedia putnami survey at Horsetooth Mountain Open Space by Tim McNary) and Okanagana (see Predator avoidance leads to separate emergence cycles in the protoperiodical Okanagana magnifica).

Considering there would only be Periodical stragglers in 2023, it was a perfect year for an iNaturalist project focusing on cicadas that emerge annually: 2023 North American Annual Cicadas Location Project.

2023 Project

This project includes all of North America, which includes Mexico, the United States, and Canada. iNaturalist determines the geographical footprint. It seems like most of the folks using the iNaturalist app are in the United States.

Typically cicadas in the southernmost, warmest areas (Mexico, Texas) emerge first. Cicadas that have black bodies like Platypedia can tolerate colder temperatures because the sun warms them up, so they’ll emerge in northern areas before other types of cicadas.

As of September 2nd

#1 Morning Cicada, #2 Superb Dog-day Cicada, #3 Resh Cicada, #4 Northern Dog-Day Cicada, and #5 Lyric Cicada. My prediction is that the Northern Dog-Day cicada will surpass Resh in a week or so.

Platypedia putnami survey at Horsetooth Mountain Open Space by Tim McNary

Here’s a short 2021 update for the Platypedia putnami survey at Horsetooth Mountain Open Space, west of Fort Collins, Colorado. 2021 is turning out to be a very large emergence for this cicada, and it’s not through yet! The survey transect goes from the trailhead parking lot to Horsetooth Falls. Although the first exuvia found was on May 22, 2021, the bulk of the exuvia, so far, have emerged (153 of 201 exuvia) June 5-8th. “Clicking” of adults can be heard in many areas, but is concentrated in certain sites.

Okanagana Cicadas

Okanagana is a genus of cicadas that share their name with the Okanagan Lake, Valley & County areas of British Columbia, Canada. As you might guess, Okanagana are common in Canada. It is likely that the genus was named in tribute to the Okanagan people.

West of the Mississippi, O. synodica synodica & O. bella are the most common species in terms of the number of states and providences they are found. O. canadensis & O. rimosa are the most common species east of the Mississippi.

Lifespans and Lifecycles:

Okanagana rimosa have a lifespan of 9 years. Okanagana synodica have a lifespan of possibly 17 to 19 years! (see Campbell et al. 10.1073/pnas.1421386112).

Okanagana rimosa also appear to be proto-periodical (source) meaning they are abundant in some years, and scarce, but not absent in others.

“Soper et al (112) showed experimentally that Okanagana rimosa had a life
cycle of 9 years, and that in the field during a 9-year period (1962 to
1970) it was extremely abundant in 4 years and scarce or absent in the
other 5. Heath (32) also studied cicadas of the genus Okanagana and
found several species that appear to be protoperiodical.”

I’m not sure, but I suppose other species of Okanagana have proto-periodical lifecycles as well. This would explain why people see Okanagana in great numbers one year, and very few in previous years.

Identification:

Okanagana are typically around between June and July, depending on the species and latitude.

Okanagana are often black, with white, beige or orange highlights on their wings and body. The black color of their exoskeletons helps them absorb warmth from the sun.

Look for four symmetrical markings on their mesonotum (back). The image at the beginning the the article highlights these markings.

One Okanagana that has atypical coloration is the O. viridis which is green. This outlier is one of the few species found in southern states.

Okanagana rimosa nymph skins

The Okanagana rimosa, also known as Say’s Cicada, is a cicada that can be found in the USA in northern states east of the Rockies, like New York, Pennsylvania, Michigan, Wisconsin, Minnesota, North Dakota and all New England states. Say’s cicada can also be found in the Quebec, Ontario, and Manitoba provinces of Canada.

Say’s Cicada is black and orange; orange legs, orange markings on its mesonotum, and orange bands around most segments of its body. Here’s a photo of an adult:

Okanagana rimosa photo by Natasha from 2005.

A few weeks ago Elias Bonaros sent us some photos of the exuvia (shed skins) of Okanagana rimosa nymphs that he found while searching for cicadas in Western Massachusetts with Gerry from Massachusetts Cicadas. It’s interesting that the black bands that appear around the segments of the nymph’s body are where we see orange bands in the adult form.

Side view

Say’s cicada has a fantastic call that needs to be heard to be appreciated. Visit the Insect Singers website to hear the call of a Okanagana rimosa.

An interesting note about the Okanagana rimosa, it has been showed to have a 9 year life cycle, and appears to be protoperiodical:

“Soper et al (112) showed experimentally that Okanagana rimosa had a life
cycle of 9 years, and that in the field during a 9-year period (1962 to
1970) it was extremely abundant in 4 years and scarce or absent in the
other 5. Heath (32) also studied cicadas of the genus Okanagana and
found several species that appear to be protoperiodical.”

Have you seen an unusually large number of cicadas this year?

Cicada.

Chris Simon a Professor, Ecology & Evolutionary Biology from the University of Connecticut asked us to post this on our site, and so we did.

Dear Cicadamaniacs,

If you have seen unusually large numbers of cicadas this year (or
last),and have not seen such numbers for a long time, can you please
report them to me? Chris dot Simon at UCONN dot edu? Please report
the location in which you saw the cicada, what month and year, how
long it has been since you have seen a similar emergence magnitude.

This seems to be an unusually good cicada year, maybe related to
unusually wet or otherwise favorable weather:

Dan Johnson from Southern Alberta, Canada reported an outbreak of
Okanagana synodica this year. He says: “I saw only a few between
1983 and 1985, then a few per year in 1986-88, then rare again, then
slightly more in 2000-2003, and only last year did they bloom, and
really with a bang (more than 1000X). My study area is southern
Alberta and Saskatchewan, mainly mixed grass sites in Alberta, plus
fescue foothills.” He had not seen an emergence like this in the 20
years he had worked there.

John Cooley reports Okanagana rimosa and canadensis as being very
dense this year in Northern Michigan and Dan Vanderpool reported that
an unidentified species of cicada was out in Northern Idaho that
residents noted they had never heard before (at least not in big
numbers) and one respondent had lived there for 30 years.

This record was from last year: Eric Toolson of New Mexico writes-
Last year, there was a widespread & heavy emergence of Tibicen
townsendii across a rather large area of central New Mexico
grassland. Prior to that, I knew of only one population in an area
of several hundred square miles, and that occupied an area of only
about 2 hectares. That population has been emerging in good numbers
for over a decade [in this location], but I never saw the species
anywhere else within a distance of several tens of miles in any
direction. I had formed the impression that although T. townsendii
was geographically widespread, its range was occupied by a relatively
few, widely-scattered, discrete populations that were failing to
occupy what seems to be a lot of contiguous suitable habitat.

Cicadas are known for their boom and bust years. It would be nice to
start keeping track of them.

Thanks very much,

Chris
