Another world


This is a summer unlike most.
And certainly unlike any I can remember.


With each day, I think they must be gone—but, again the rhythmical chanting begins.
From high in the trees, or the grasses at my feet—they are everywhere.
Still.
Invaders from another world.

Fallen bodies litter the paths I walk.
They stumble, as in a drunken flight, bumping from one spot to the next. Orange wings clattering noisily along.
To leave a generation behind.

I wonder how this place will have changed in the 13 or 17 years before their young emerge from feeding below the earth.
And how large these small branches will have become.


And what the sky must feel like to something that has only known darkness.

“Mated females excavate a series of Y-shaped egg nests in living twigs and lay up to twenty eggs in each nest . A female may lay as many as 600 eggs. Six to ten weeks or so after oviposition, in midsummer, the eggs hatch and the new first-instar nymphs drop from the trees, burrow underground, locate a suitable rootlet for feeding, and begin their long 13- or 17-year development.”

Emergence



They're back!
Actually, they've been here all along. For the last seventeen years, that is, living beneath the ground, and feeding off the sap from tree roots.
Periodical cicadas emerge in "broods," groups sharing the same 13 or 17-year cycle, when the ground reaches about 64 degrees, usually in mid-May. But with this year's cooler spring, we found them appearing Monday. Smaller than the Dog-day cicadas of late summer, periodical cicadas are black, with bright red eyes.

And, although they may look pretty scary, they're harmless.
Some even say they're delicious!





If you live near one of these little red dots, you're probably seeing them too!

We're fortunate to have one of the foremost cicada experts living in the Cincinnati area.
Dr. Gene Kritsky has more detailed information on his website.
