"Why Cicadas?"
Cicadas are perhaps the most intriguing
insects that I've ever come across. Not to say that I'm an expert in
Entomology because I'm not but from what I've learned about this species
has kept my interest in Cicada's for many a year. I remember when I
first ran across the Tibicen species, it was in Baltimore City. Though
it was 30 years ago, I still remember it like it was yesterday.
"Where?"
I grew up in a neighborhood off
of Bel Air Road and Eastern Avenue. Our neighborhood consisted of three
main streets; Mareco (where I lived), Lawnview and Cliftmont avenues.
These three streets were bisected down the middle with Annetta Avenue
giving our neighborhood 6 blocks total (3 blocks on one side of Annetta
and 3 blocks on the other). As a matter of fact, you might even say
that our neighborhood is famous. If you've seen the movie "Tin
Men" starring Danny DeVito and Richard Dreyfuss there are a few
shots of Cliftmont Avenue in that movie as the majority of the film
was filmed right in Baltimore.
But I digress; this was supposed
to be about Cicada's wasn't it?
"Step into the Way-back
Machine...."
My first Cicada experience was
at the neighborhood vacant lot bordering Annetta Avenue and one of the
many back alleys that ran behind the row houses in which we lived. I
was around 10 years old at the time. I remember it was hot and my friend
Tom and I were waiting for the rest of the neighborhood gang to meet
us down at the vacant lot to get a game of touch-football going. While
I was growing up, the vacant lot was the neighborhood gathering place.
Girls and boys alike would gather here to socialize.
"What the heck?"
While waiting for the rest of our
friends to arrive and being very bored, I turned over a large rock.
Underneath was this rather large bug. I remember as soon as I turned
the rock over, the bug was all a-blur because it kept on fluttering
and flicking and buzzing along the ground. All the buzzing startled
me so I immediately turned the rock back over to cover the bug and I
called my friend Tom over. "Hey, Tommy you're never gonna believe
this! Watch when I turn this rock over." Sure enough when I turned
the rock over, again the bug started fluttering and flicking and buzzing
along the ground. Tommy jumped back startled so I turned the rock back
over on it again.
Looking at me eyes very wide he
said, "Hey, did you see that?"
"Yeah."
"What do you think it is?"
"I have no idea, maybe we should get your dad."
The back of Tom's house bordered
the vacant lot and both of us ran toward it. While running, Tom was
yelling "Dad! Dad! Come here! We need to show you something!"
"Shock and Awe!"
Toms father; who, judging by the
way his son was yelling, thought that we must've found a dead body or
something. He came running out of the house, "What's wrong?"
I answered, "We found a big bug under a rock!" and Tom added,
"Yeah and it's as big as a horse!"
"A reality check."
Walking back towards the vacant
lot and the rock, looking at Tom, Tom's father said, "Now Tom,
stop exaggerating, if it was as big as a horse, it wouldn't fit under
a rock now would it?" Smiling sheepishly Tom replied, "Sorry
dad but you gotta see this bug, it's really big."
"Great expectations
deflated."
Kneeling over the rock I grasped
it and looked at Tom's father. "Are you ready?"
"Yes." He replied. I
carefully turned the rock over. By this time the bug wasn't flapping
and fluttering. It was just there nice and quiet. Tom and I together
looked up at his father in anticipation of his reaction. Picking it
up he said, "Oh, that's just a locust." Tom and I both felt
a little deflated at his response to seeing an insect that we've surely
hadn't seen before in our young lives.
"That can't be right...can
it?"
When he said it was a "locust"
I thought that I didn't hear him right so I said "A what?"
He replied, "A locust. A heat-bug. They come out every summer and
are quite common. I'm surprised you boys haven't seen these before.
They make that strange sound in the trees during the summer."
Thinking back to Sunday school
and how the instructor talked about the plagues of locusts visited on
people during the time of Jesus, I thought that locusts were grasshoppers
and this surely wasn't any grasshopper that I've ever seen.
"Don't ask questions
if you know what's good for you."
Being intimidated by Tom's father
I decided to keep my mouth shut and not ask too many questions. After
all, we dragged him out of his air-conditioned house to look at a bug.
Tom's father handed the locust
to his son and walked back up to the house and that was that. That was
my first exposure to a Cicada (which at the time I thought of as a locust).
Now I know what you must be thinking.
Especially if you know about the lifecycles of Cicadas. You're probably
thinking we definately didn't find a true Cicada but maybe what we thought
was a Cicada because Cicadas are not known to be found under rocks.
But I tell you, I found this Cicada under a rock.
"Our time with Lucky."
Tom and I were fascinated by this
locust and even took turns keeping it at each other's house. While handling
the locust it kept making the buzzing alarm sounds. We even named it
"Lucky the Locust" because we felt "lucky" to have
caught one. We were very upset when it died. We caught several different
locusts that summer and I remember that they all never really did live
long. Maybe two to three days maximum.
"A logical conclusion."
Thinking back over the years I
have concluded that perhaps this Cicada's emergence hole just happened
to be under a rock. (This is assuming that you already know something
about the life cycles of Cicadas). After all if you read the account
above you will see that I was able to turn the rock over then back onto
the Cicada several times without harming it. Perhaps there was a hollow
area where the rock met the ground that was large enough for Lucky to
crawl out and do his molting. In all our excitement of that day, I do
not remember seeing Lucky's exuvium but it could of been there and at
that time I was unfamiliar with the lifecycle of Cicadas.
"The hunt begins!!"
During that summer Tom and I continued
to look under various rocks in the hopes of finding other Cicadas. I
have not been fortunate to find any other Cicadas emerging from the
ground under rocks. Lucky was the only Cicada that I have ever found
this way.
We were surprised at how easy they
were to catch because they liked to stay in low bushes and their calling
sound attracted us. It was during this time that we learned that the
males called for females and that females were silent. We were also
surprised to discover that there were different species of "locusts"
in our neighborhood with the males making very different calling sounds.
We liked to catch the males because of course they were the easiest
to catch and we liked their alarm calls when captured.
"The quest for knowledge."
Seeking more information on these
"locusts" that we were catching, I remember going to my local
library that was within walking distance of my house. The library was
on Erdman Avenue known as the "Enoch Pratt Free Library".
Walking up to the Librarian I asked for information on "locusts".
She showed me a book on insects on the subject and in the book was a
picture of a locust. As I previously suspected, a locust was actually
a winged grasshopper. When I explained to her what my friend and I had
found and caught during that summer she said, "That sounds like
a Cicada. A common mistake when it comes to indentifying this insect."
She turned to a picture in the
same book and I exclaimed, "That's it!! That's what my friend and
I caught!" I told Tom what they were actually known as and that
there were many many different species all over the world. He was totally
amazed. Looking back now, the actual species that Lucky the Locust was,
was a Tibicen
chloromera.
"That's not entirely
accurate."
We learned in books of that era
(back in the 70's) that there were actually 5, 7, 13 and 17 year periodical
Cicadas and 1 - 3 year Annual Cicadas. It was only later through the
years that I learned that there are no such thing as 5 or 7-year periodical
Cicadas. There is a species that comes close and that is the Okanagana
rimosa species which have a 4 year life cycle.*
We also learned that Cicadas actually
live under ground during those years in a stage known as a "nymph".
When they were below the ground in their nymph stage they feed off of
the juices of tree roots. When they emerged from the ground, whatever
nourishment they obtained from all the years feeding off of tree roots
during their nymph stage was designed to sustain them for their 1 to
2 week period above ground and that they had no mouths for eating.
This later also proved to be a
false fact. I can remember when I was a boy that one Cicada in particular
would try to insert a rigid long tube-like appendage into my skin. At
the time, I thought that it was trying to sting me without much success
because while it was only slightly uncomfortable, it didn't really do
any damage. This tube-like mouth part is actually designed to penetrate
branches of trees and that the juices of the trees could be "sucked-up"
through this appendage for nourishment and to help the Cicada avoid
dehydration.
We learned that when they emerged
from the ground, that their sole purpose was to mate and the female
to lay her eggs in the branches of trees then both males and females
die.
Annual Cicadas actually live underground
1 to 2 years at the most.** The fact that they lived underground in
varying stages of nymphs for so long we found totally facinating and
started looking for nymphs as they emerged from the ground at night.
But unfortunately while we found
many discarded nymph shells or "exuvia" and also many exit
tunnels around trees, we were never fortunate to discover Cicada nymphs
emerging from the ground. I suspect that they would start to emerge
well after we were in bed at night.
"The cicada with
the fiery red eyes."
We also learned at that time about
the Periodical Cicadas that emerge every 13 and 17 years. We
were fascinated by their fiery red eyes and orange transparent wings
and the fact that they lived under ground for 13 or 17 years depending
on your location. We couldn't wait until they emerged in our area. The
books we had access to didn't break down for us the different broods
nor the years of their emergence but I remember hoping every year that
we would see these Periodical Cicadas.
"A new interest and
new direction."
The following summers were spent
catching Cicadas and other insects like Praying Mantises and Katydids.
We were interested in Katydids because they made a similar noise to
Cicadas - at least to our young ears and we were interested in Praying
Mantises because quite frankly, they were brutal and we were fascinated
with how they devoured other insects like the Daddy Long-Legs (Harvestmen
Opiliones).
But slowly over time as one
grows older, one's interests change through the years and fate steers
us down different paths. My interests turned more towards girls and
cars in my teenage years and Tom's life was going down a very different
direction than mine. But still, whenever I heard a Cicada's call my
head would turn...
I left the Baltimore area
in 1980 returning from time to time to visit my family after moving
to New England. Over the years whenever I visited Maryland, if I heard
an Annual Cicada calling in a tree or bush, I actually resisted
the urge to go see if I could find it and catch it. I actually felt
kinda silly for even thinking about trying to catch one after all this
time. "Catching bugs was for little boys with wads of chewing
gum between their cheek and gum, dirty hands, scraped knees and baseball
cards in their back pockets.", I thought.
But even to this day, the
urge has always been there and whenever I hear a Cicada calling, it
takes me back to those hot nights growing up in Baltimore with my friend
Tom by my side running around like chickens with our heads missing trying
to catch a Tibicen every time we heard them call.

- "Soper et al. found that the life cycle was approximately 9 years
but they do have heavy emergences every 3 or 4 or 5 years and light
emergences in between." Thanks Chris
