Emergence of Prime Numbers as the Result of Evolutionary Strategy

Filed under: Magicicada | Periodical — Dan @ 4:12 am

Professor Douglas Galvao of the State University of Campinas has written a paper titled Emergence of Prime Numbers as the Result of Evolutionary Strategy. He is hoping to get feedback from the scientific / cicada community.

We investigate by means of a simple theoretical model the emergence of prime numbers as life cycles, as those seen for some species of cicadas.

You can download a PDF version of the paper. Windows users will need Adobe Acrobat Reader to view it, and Mac users can simply use Preview.

$50 Reward for Cicadas

Filed under: Brood XI | John Cooley | Magicicada | Periodical Stragglers — Dan @ 10:07 am

Hey folks, I just got this message from John Cooley, a cicada researcher:

Have I got a deal for you……..see the attached. We’re hoping to
mobilize the cicada fan club to see whether our local brood really
has gone extinct (I think it has- no sightings at last known patch in
1971, 1988, or 2005).

There’s more info about this on Cicada Central— I’ll also consider
some sort of a reward for significant collections of live M.
septendecim stragglers from the eastern part of Brood X, and I’ll
grant the full reward for XI specimens in the CT river valley of MA
and CT, as well as anywhere in RI.

So, if you find a Magicicada in those areas, and have proof, please contact John.

Cooley Reward.

Straggler Cicadas in Yellow Springs, Ohio

Filed under: Magicicada | Periodical Stragglers — Dan @ 8:12 am

Greg Spahr reports from John Bryan State Park in Yellow Springs, Ohio:

I was out birdwatching yesterday and was shocked and surprised to hear a few Magicicada Cassini calling. I didn’t know about the stragglers until I got on the web and found the reports on your site. In any case, I could hear about 10 individuals calling at John Bryan State Park in Yellow Springs, Ohio yesterday (June 5th).

From 5 Channel Cinncinati:

Pesky Cicadas Are Back
1,000 Stragglers Could Pop Up This Summer

CINCINNATI — Tri-staters thought they saw the last of the cicadas for a few years, but a local woman is saying they’re back.

Target 5’s Michelle Hopkins checked into the situation and found proof — a dead cicada that lived about three days in Springfield Township.

Brood XI: Alive?

Filed under: Brood XI | Magicicada — Dan @ 11:29 am

It is possible that Brood XI is not extinct. Brood XI hasn’t been recorded since in 1950’s, however, David Marshall of the University of Connecticut “would not be surprised if there are small patches of them that have been missed since much of southern New England is not that densely inhabited”.

If you’re in the Connecticut, Massachusetts, or Rhode Island area this spring and you hear or see a Magicicada, please let us know.
