Are you annoyed?

I woke up in the middle of the night wondering where the chirping sound coming from, then I realized it was the crickets inside the insect box. I put my ear plugs on, turned around and got back to sleep.

The next morning, the crickets were still chirping and it was getting louder and louder. By just listening to the patterns, there seemed to be two different crickets chirping, one after another. Out of curiosity, I took my camera and taped a closeup video to see how they made the sound.

In animal kingdom, it's always the males dancing around or doing beautiful callings to attract females. The crickets are no different, except there are three other conditions for which they chirp – first, while falling in love. Second, while bullying each other, and finally, alerting others danger approaching.

If you watch the video, you'll know both crickets are rubbing its own wing against the wrinkles on the other wing to make the sound. And you can tell their chirps are aggressively aiming at each other, obviously a power struggle. It's so amusing to see it in a close up.
