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.
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.
