The Lesser Antilles Cicada aka Chalumalna martinesis is a cicada found in the Lesser Antilles islands, for certain in Saint Martin (see sightings on iNaturalist).
Cicada researcher Allen Sanbornhas a new paper titled Redescription, illustration and higher taxonomy of the Lesser Antilles cicada Chalumalna martinesis Boulard, 2001 (Hemiptera: Cicadidae: Cicadettinae).
This paper is of particular interest as it places Chalumalna martinesis this cicada in the Trible Lamotialnini, which is the same Trible as Magicicada periodical cicadas found un the U.S.
From the Abstract:
The genus Chalumalna is reassigned to Lamotialnini Boulard, 1976 based on the presence of conjunctival claws on the aedeagus and the lack of a developed uncus. Brevialavenosa Sanborn, 2021 and Chrysolasia Moulds, 2003 are shown to be members of Lamotialnini as well, expanding the tribal distribution to include the Caribbean, South and Central America.
Looks like there is a new sub-species of Megatibicen pronotalis, to go with Megatibicen pronotalis pronotalis (Davis, 1938) and Megatibicen pronotalis walkeri (Metcalf, 1955) called Megatibicen pronotalis hesperiu. I am going to guess that ‘hesperiu’ refers to the Greek word for evening or western. If it’s western, maybe the hesperiu is an offshoot of M. pronotalis pronotalis.
Looking at data from Google Trends(columns) and iNaturalist(lines), it looks like 2024 will be the best year in over ten years, with 2020, 2017 and 2013 being peak years (but not the biggest). iNaturalist is also a relatively new app/website; my guess is its user base wasn’t big enough until 2019 to compare to Google Trends.
While some Green Grocers appear every year, there is a periodicity at play. With the little data below it would seem there are two 7 year groups: one 2013 to 2020, and one 2017 to 2024. I’m making assumptions.
If my boss fires me tomorrow, I’m headed to Australia.
Most of my cicada experience happens in the state of New Jersey, particularly central New Jersey (which does exist: it is comprised of Middlesex, Sommerset, Hunterdon and Mercer counties). Typically, in central and northern New Jersey, the summer cicada season will kick off in late June with the emergence of Neotibicen lyricen and end with the grinding calls of Neotibicen canicularis in the middle of September. Central New Jersey has these annual cicada species: Neotibicen lyricen (both sub-species), Neotibicen linnei, Neotibicen tibicen, Neotibicen winnemanna, Neotibicen canicularis, and possibly Megatibicen grossus in the south, and Okanagana rimosa in the north-west. Periodical cicadas are also found in the area, but not in the summer, and not in 2024.
Neotibicen tibicen aka Morning Cicadas (most call them Swamp Cicadas — I do not because it is not a helpful description) are abundant in my location and do well with both Spruce and Maple trees.
The summer of 2024 was a strange one:
I didn’t find my first Morning (Neotibicen tibicen tibicen) cicada until July 7th (about a week late), found my last one on August 9th (about two weeks early).
The last cicada I heard sing was during the last week of August, about two weeks early.
June high temperatures were 5 degrees Fahrenheit hotter than average (avg. 1991-2020), and there was 30% less precipitation. A HOT and DRY start.
July high temperatures were 2 degrees Fahrenheit hotter than average (avg. 1991-2020), and there was 20% less precipitation. A hot and DRY mid-season.
August high temps were flat, but there was +51% more precipitation. Average temperatures, and wet finale.
Neotibicen cicadas are around every where, but there are good years and great years. 2024 was not great. I don’t know if the extra HOT and dry weather had an impact, but it may have. Lots of “maybes”.
Here’s some photos of molting Neotibicen tibicen for you to enjoy:
Bladder Cicadas are out in Australia, as reported by Ben McBurney on the Facebook Cicada Science & Discussion group.
Bladder Cicadas are green, sing at night, and have large abdomens. Are they katydid mimics, or just filling the same niche? Seems like it. According to Ben they sound like frogs, so maybe they’re frog mimics as well.
How rare are Magicicadas cicadas with white or blue eyes?
Do we include yellowish-white/cream-colored eyes? Gray eyes?
“One in a million!”
“One in 100,000?”
“One in 1000”?
Let’s look at some data. Since its beginning, as of June 19th, 2024, iNaturalist has had 27,294 Research Grade Magicicada sightings, and 136 Research Grade “Magicicada eye color=blue/white” cicadas. So, in the iNaturalist data set, one in 201 Magicicada have white or blue eyes.
The number of white/blue eyed Magicicada is without a doubt more than one in 201, but not one in a million. Personally, I’ve found at least one cicada with white or blue eyes per emergence. My guess is the number is closer to one in 10,000.
But don’t tell anyone who is excited about a one in a million find. Let them have their fun and happiness. 🙂
As I write this, the Brood XIX emergence is all but over, and Brood XIII has about two weeks left to go.
So what’s next? Well, I’ll tell you.
Upload your photos to iNaturalist and the Cicada Safari app
You can help cicada researchers by uploading your photos to iNaturalist or the Cicada Safari app.
iNaturalist is excellent for all animals — plus plants and fungi — not just cicadas. You will find yourself using it all year long. Cicada Safari is specifically for cicadas.

There are more to cicadas that just Periodical cicadas.
Cicadas exist on every continent except for Antarctica, and in every State in the U.S. except for Hawaii and Alaska!
Saving cicada skins (molts/shells) and wings is easy. Just keep them dry.
Preserving Periodical cicadas can be challenging because their eye colors fade and because they’re fatty and smell.
If you want to preserve eye colors, keeping them in alcohol seems to work best.
Some people dip them in acetone to mitigate the smell from decaying fat, but I’ve never tried it.
Otherwise, keep them dry and in a cedar box. I use silica gel packs to keep them dry. Cedar repels small insects that will eat your cicada collection. Moth balls work as well to keep tiny insects away from your collection.
If you want to pin your cicadas, so the wings are spread out, you have to do it while the cicadas are still moist. Plenty of places have supplies, like Carolina Biological Supply. I’ve softened hard cicadas by placing them in Tupperware/Rubbermaid containers with moist paper towels and a moth ball to prevent mold.
Make a scrapbook of your cicada memories
Make a scrapbook or photo album of your cicada memories.
This is something I do every year, though I tend to mix it up with non-cicada photos as well.
Periodical cicada Brood XIV (14) will emerge in the spring of 2025 in Georgia, Kentucky, Indiana, Massachusetts, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia. The last time this brood emerged was in 2008. Special note: removing Maryland from the list at the request of the State Entomologist of Maryland. There might be some Brood Xstragglers in Maryland.
It looks like the first adult Magicicada was signed in Tennessee. See the report on iNaturalist. This could be a straggler from another brood.
Usually beginning in May and ending in late June. These cicadas emerge approximately when the soil 8″ beneath the ground reaches approximately 64 degrees Fahrenheit. Above ground temperatures in the 70’s-80’s help warm the soil to that point. A warm rain will often trigger an emergence.
Other tips: these cicadas will emerge after the trees have grown leaves, and, according to my own observation, around the same time Iris flowers bloom.

*City data comes from May 2008 and June 2008 blog comments. County locations are historical and may no-longer be accurate.
Experts (Gaye Williams, State Entomologist of Maryland, John Cooley of UCONN) have confirmed that there will be no Brood XIV cicadas for Maryland. That said, there will be some stragglers from Brood X. You can look for reports of stragglers using this iNaturalist map.

Cicadas @ UCONN has the most up to date maps. Zoom in and look for the images of cicadas.
* Although county locations may no longer be accurate, I like to keep them on the page in case someone discovers a small, secret or unknown population of these cicadas. People might be disappointed, but we want to know for sure that the cicadas are (or are not) thriving in historical locations. This is the cicada researcher’s dilemma: either focus on the guaranteed/sure shot locations for the general public to enjoy, or include the obscure, relic locations so we do not miss out on rare cicada sightings. Cicadas @ UCONN talks about the relationship between the different broods — Brood XIV and Brood X are closely related geographically and genetically. You might find a Brood X straggler emerging 4 years late, and mistake it for Brood XIV. If a large number (large enough to sustain future emergences) of Brood X makes the 4-year “JUMP” to be in synch with Brood XIV, they technically become Brood XIV (and the reverse is true).
