It's *possible* I'm a bit of a science geek

They're heeeeee-rrrrrrrrreeee!

What, you ask?

Why, the Great Southern Brood.

Also known as Brood XIX.

Also known as Brood XIX magicicada tredecim and magicicada neotredicim.


Also known as the 13-year periodic loudest summer you can imagine!

(If you're not a bug person.  You should look away.  Really.  Don't say I didn't warn you!)

It's time for 13-year CICADAS!

It's time for this:
Adult cicadas and left over husks after molting.
 And, this:

And, this:
Adult cicada (on top) with empty husk of a nymph.
Throughout the Midwestern US, a 13-year brood of cicadas has been emerging from the ground over the past few weeks.  They just started coming out in my town last week.  For those who are in this area, or have experienced this in other areas, you know what I'm talking about.  Suddenly, no matter where you look, there are bugs EVERYWHERE.  At twilight, the brown nymphs start to emerge from the ground and climb until they find a nice leaf or tree branch or truck tire or brand new wood frame your husband has been building for hours or, if you stand still long enough, your leg.  They settle in for a bit and then slowly, over the course of half an hour or so, start to molt off their skin and emerge new and creamy white with bright red eyes and black spots.  They pump fluid into their wings until they are full and translucent and then hang out while their bodies harden and darken to black or orange-ish.  Give them several days and they start screaming (well, kinda) at each other as they mate.  We're talking millions around here or, reportedly, billions in the entire brood (which is spread across the Midwest and part of the South).  After the females lay eggs in tree branches, the eggs hatch, and the tiny white juveniles make their way back into the ground, dig around a bit and hang out for 13 years sucking on tree sap until they're ready to emerge again.

There are 13-year and 17-year species of these types of periodic cicadas but nothing in between.  Isn't that bizarre?  I just find that amazing.  The last time these guys were here was 1998.  I moved to the area in 2002, so this is the first time I've seen them.  They're truly fascinating.  (Now, they haven't started screaming en masse, yet, so we'll see how fascinating they are at that point.)  ETA: By the time I left my office today, they started "screaming" -- it's crazy loud but still fascinating!!

It's possible that my husband and I spent several hours watching them on Sunday.  And again on Monday.  It's possible that I took over 200 pictures.  It's possible that I sat in a really awkward position for over an hour watching one particular late emerging nymph slowly molt.  And, named him George.  And, took pictures.  (I think George was a "he."  I learned later how to identify male/female cicadas but I didn't get an "underside" view of George.  And, I now suspect he might be a she...)

George molting over about 45 minutes.
George's wings developing over about 15 minutes.
 
George's shell hardening over the course of an hour.
I was kind of sad when I realized George's wings weren't developing properly.  (I told my husband I'd love him anyway.)  There are quite a few hopping around with one or both wings that didn't quite develop.  They're more obvious because they can't fly to higher trees.  I don't know if they'll breed or not.  There's an IF connection in there somewhere, I'm sure.

Most of the cicadas come out of the ground at night and our fences and trees were covered in nymphs molting.  Here's what George's wings should have looked like.  Beautiful, isn't it?  (In a creepy bug kind of way, I realize...)

Newly emerged "teneral" cicada.
Anyway, it's been a fun distraction.

Anyone else out there being bombarded by bugs?

  1. We're out in California, so we don't get the cool bug invasions...we just have earthquakes and droughts. I am kind of jealous! Great pictures!!!

  2. I think we had cicadas a few years ago. Now the only bug invading my house is the stink bug. Not as cool!

  4. you are so patient to sit there and watch the whole thing. i would have given up about 5 minutes in! ha ha! our problem here is stink bugs. yuk! i think i'd take the cicadas over them any day, especially since they only come out every 13 years. the stink bugs are annual. :(

  5. OMG, the 17-year bastards came out in Maryland when I was in 8th grade. Grossest thing ever. You couldn't step outside with having them kamikaze you. ::: shudders :::

  6. Cicadas scare the bajeebers out of me!!! For some reason, ever since I was a kid and lived in the Nevada desert, cicadas have LOVED to jump in my hair!!!!! I've since had that happen when I've been in the southern states of the US, Japan and Greece!!! I swear they stalk me and even if my hair does look like a super comfy cicada nest, it gives them no right to bombard me! My friends of course think it's hilarious and I have been gifted a small collection of cicada-themed dolls, toys, art and collectibles. I'm glad I live in NCAL...no cicadas!!

  7. I was a little grossed out when I first started reading, but I have to say, now I'm a bit fascinated. Great pics!

  8. WOW, I never knew that cicadas had a periodic hatching. Here in CO we don't have them but when I stayed in TX for a couple months about 15 years ago I remember sitting on the porch listening to them and finding it a very peaceful noise. I'm rooting for little George or Georgette as the case may be =) Love that you named him...I name all kinds of animals that live in our yard...squirrels, bunnies, lady bugs, etc. Also extremely funny that you learned how the sex cicadas!

  9. Haha... I live in the midwest and haven't seen the bombardment, but I love you for making this post.

  10. It's times like these when I'm very glad we moved back to Florida from Nashville. Those nasty things are rampant up there, and I'm serious - I would not be able to go outside AT ALL if I were surrounded by those things. Eek! Talk about nightmares!

  14. I experienced these 'things' for the first time a couple of years ago when I was visiting in NC. I have to say, I was just grossed out by them! And I did have some girly-screaming moments when they flew at me or squirted some liquid as I accidentally bugged (pun intended) them.
    Glad to see you are having fun with them, you can keep them. :D
