Is anyone here gonna be collecting the 17-year cicadas when they emerge? If you are, i'll pay you money if you save 10-15 of them and ship them to me. I don't want to miss out on them when they emerge.

I am really looking forward to it. Last time they emerged I was 3 years old, haha. I will certainly collect some extras if they are indeed in my area again.

I would appreciate it if people would add an update when they start emerging in their area. I'm a couple hours outside the expected area and will drive over into TN or KY, assuming I don't miss them. Thanks in advance.
Also, if I do end up collecting some I'd be happy to save some as well.

Does anyone already encounter them in upper states.
I wonder when to expect them in southern Ontario.
Any updates ?

No Ontario and barely NY. Do a search there are dozens of maps.

Ah, I saw some maps that mark Ohio and New York states but they were misleading. Although they occur south of Lake Erie I wonder if they crossed the lake.

Having never seen a 17 year cicada emergence, it finally gnawed on me enough, so this past weekend we travelled to south central PA. It was worth the trip!
These Brood X behave completely differently than "normal" cicadas as follows:
1. There are literally thousands per sq. km.
2. The volume is not shrill, but like a constant drone. They are not as loud individually, but with so many the sound is a constant buzz/ hum.
3. Barely fly. Longest flight I saw was maybe 20 meters; most flights 3-4 meters. No flight control; no turning, just a crash land.
4. Dumb as stumps. I never considered cicadas to be particularly bright, even for insects. These things crashed into the vehicle, and would fly down into the road, full speed.
5. "Full speed" isn't very fast, maybe 10kph at best.
6. Most were not high in the trees, instead only 1- 3 meters above ground.
7. When disturbed by walking through the brush they acted more like grasshoppers- scattered, willy-nilly in any direction, short distances.
They were everywhere, on every plant. The road is littered with dead bodies. I saw Liminitis astyanax feeding on a dead one in the road.
It may have been a once in a lifetime experience for me. It was awe inspiring, and freaky.

I have been fortunate to see this event occur three times (here in Illinois) during my lifetime.
In 1973, 1990, and 2007.
Your observances are right on; and yes periodical cicadas do exhibit quite different overall behavior from the (typical) annual cicadas.
I must agree that cicadas generally give one the impression that they are not the "brightest bulb in the box".
However, surprisingly (amongst annual cicadas) their "fright/flight" response is very reactive and almost instantaneous should a bird or anything else get anywhere near them while they are chorusing.
I have seen them take off and pull some of the most "amazing maneuvers" to get away from something that is trying to catch them. One could say they almost look like they are sometimes pulling g's with their crazy turns and pitches.
Despite all these efforts I have still seen some get caught in mid-air but, I have also seen as many get away to live another day. It seems to be about a 50/50 deal as far as living or being eaten.
They may not hover or fly backwards as a dragonfly can but, their Aerial acrobatics of escape are truly note worthy; one could say similar to a fighter jet pulling g's and tight turns through a labyrinth of mountain passes !
I do have a certain admiration for cicadas in their own right.

Another casual observation that I have made over the years regarding annual cicadas is that they really lead active lives up until the very end when they have literally expended themselves.
Once the newly emerged adults have dried their wings they are busy creatures.
Males spend the day chorusing and flitting from tree to tree in the hopes of attracting mates. Females once mated spend their time largely laying their eggs except to feed.
Only occasionally will one be attracted to a light. However, after the males have perhaps had several matings or have battered their wings fairly badly they then seem to go to lights more readily as well as the females who have probably expended all their eggs.
It is at this late stage in their life that you can find them either late at night at street lights or at building lights and oftentimes you can go to that same location the next day and find them still there but, dead.
I have found them many times in this way the following day --usually food for ants.
A fitting end I suppose when you have spent your life singing happily in the trees, flying all about everywhere, and carrying on your species once again...
Annual cicadas in my region can readily be found at lights during the second and third weeks of September here in the Great lakes region.

Cicadas are cool, I remember the first time I found an adult nymph crawling on the ground, I didn't know what it was, but spent the rest
of the afternoon watching it crawl onto a plant, and break out of the nymph shell. It took a looonnngg time.
And, while I'm logged in adding to this thread- "brood X"? What does that mean? Sounds like an alien movie.

Hey Kevin,
A brood is a population of cicadas isolated
from all others by year of emergence or locality.
Brood X (X is 10 in Roman numerals) is the largest
brood of 17-year cicadas. This particular brood is
found in three separate areas centering around
Pennsylvania and northern Virginia, Indiana, and
eastern Tennessee generally speaking.
There are actually 3 species that I am aware of
(at least in my state / Ill.) but, I read recently
another "new" species was recently described !
All told their are 12 broods of 17-year cicadas and
a further 3 broods of 13-year cicadas.
Hope this clarifies things somewhat.

I was worried that it was something to do with generation x... I had supposed that over time 17 year cicadas would have had broods stretched out
over time, and you did clarify it nicely, thanks.

Not so much as one periodical cicada here in Northern Indiana.

Hey Tim, good to see you back on the forum !
There are a few of the upper Northwest counties of Indiana which actually fall under the umbrella of brood XIII.
That brood (which is part of the northern Ill. region) will not emerge until 2024.
It looks like the greater portion of Indiana falls under brood X which of course emerged this year.
Brood X should be near finished by now as periodical cicadas tend to be late spring and early summer emergences. By the first week of July (or so) they're really quite done for a long time...
