Dog-Day Cicada vs. Periodical Cicada in Tennessee

Dog-Day Cicada vs. Periodical Cicada

The Bug Man brings clarity in this year of cicada confusion by tackling the issue of periodical cicadas versus dog-day cicadas. As Tennesseans gear up for football season (Go Blue Raiders!), the days are getting cooler and the brisk air of autumn is gradually blowing in. The familiar sound of cicadas singing in unison signals that the day is ending and night is about to fall.

How peaceful…

Hold up! Hold on! Wait…

Here ends the serenity and begins the confusion.

Cicadas? I thought they were locusts. Didn’t we just get rid of the cicadas? Don’t I hear some bug singing every summer? What is going on?

Many Middle Tennesseans are still reeling from the 2011 cicada invasion. Memories of bug attacks and mass open cicada graves are still burned into our minds.

Suddenly that peaceful twilight scene described above is full of fear and annoyance.

Here’s the deal. What we went through earlier this summer was a rare occurrence. A once-in-every-thirteen-years occurrence. Those periodical cicadas had black bodies and red eyes. They came out by the millions to terrorize innocent humans. Please read our blog entitled The 13-Year Cicadas Set to Invade Middle Tennessee for more info on what happened.

What we’re experiencing right now is “normal.” It happens every year. These cicadas have green bodies and black eyes. Their population is much smaller. And you most likely will not see them swarming around all over the place.

You or someone you know may have called these bugs locusts. However, they are not. Locusts are a type of grasshopper. Cicadas are leafhoppers/froghoppers. Maybe we should just call them hoppers. That way everybody wins. 🙂

Here at The Bug Man, we’re big fans of humor. It’s great to laugh! Because, honestly, some things are quite funny. If laughter is the best medicine, then we’ve got an entire medicine cabinet full of it!

While browsing Twitter today, we stumbled upon a funny little web page called Llama Font. It genuinely cracked us up to think about Tina the llama from the movie Napoleon Dynamite bending to make llama letters.

The creators of Llama Font suggested that their llama letters should be used to deliver bad news…

The 13-Year Cicadas Set to Invade Middle Tennessee

The cicadas are coming!

The cicadas are coming!

The cicadas are coming! You may have heard rumors that the dreaded 13-year cicadas are emerging this year in Tennessee. It’s true. They are coming between April and June.

You may have heard rumors that the dreaded 13-year cicadas are emerging this year in Tennessee. It’s true. They are coming between April and June. It is predicted that they will appear when the ground temperature reaches 64 degrees Fahrenheit. Several have been spotted in the area already. In no time, there will be thousands of them!

What exactly are the 13-year cicadas? And why are they coming out this year? Don’t they come out every year? What makes this year special? What’s the difference between a 13-year and a 17-year cicada? What’s the difference between a cicada and a locust?

Cicadas are known for their beady little eyes. Contrary to popular myth, they are not blind. They can see just fine. However, fine eyesight does not prevent them from flying onto humans occasionally.

There are several different types of cicadas. You’re probably familiar with the annual cicadas that come out every summer, typically called dog-day cicadas. The rarer 13- and 17-year cicadas are growing underground all the time, feeding on nutrients in trees, but only come out after they’ve fully grown (after 13 or 17 years). The difference between a 13-year and a 17-year cicada is that one species simply takes four years longer to mature than the other.

When the 13-year cicadas appear and make a loud racket, it’s called an emergence. After maturing and growing into adulthood underground for 13 years–they are ready to emerge above ground and begin mating. The loud sound that you hear comes from the males. It’s their mating call. The females hear the mating call, find the males, mate and then lay their eggs in tree branches. Check out this informational page from The Tennessean for more details.

The reason the cicada emergence is so loud is because millions of cicada babies grew into adulthood underground together for 13 years. Then those millions appear above ground singing together in a shrieking chorus, ready to mate and create millions more babies. It’s an ongoing cycle.

The 13-year cicadas sing loudest during the hottest parts of day. They do sing at night, but not as frequently or as loudly. If you hear singing at night, it’s most likely a cricket, katydid or frog.

At The Bug Man, we don’t treat for cicadas because treating them with pesticides has proved ineffective. Other than producing a loud and annoying noise, cicadas are not harmful to humans. They don’t attack or sting. They don’t destroy the wood in houses.

However, if you have young trees growing in your yard, it’s recommended that you cover them with bird netting or cheese cloth, or to delay pruning until the cicadas have left because female cicadas cut and pierce the branches of young trees, making the trees weak.

Also, if you were planning on any outdoor painting project this summer, perhaps you should reschedule to another time because flying cicadas might ruin your paint job.

Although cicadas are often called locusts, they are not synonymous. Locusts are short-horned grasshoppers. Cicadas are an entirely different, plant-sucking creature.

The 13-year cicadas are a mysterious thing. Many people don’t understand this phenomenon and will respond in fear. If this blog was helpful and informative to you, please forward it along to your friends and family. Hopefully knowing more about cicadas will help you endure their courtship choruses.
