Ethogram: an Observation of Crickets

Cricket Behaviors


For how long did the cricket do this?

Resting- is remaining still, standing on the ground or the top/side of an object.

Walking- is using legs to move self forward across a surface

Hiding- resting in a Dixie-cup house or under objects/dirt.


How many times/how often does it occur?

Climbing- is actively crawling up an object in the container, often remain on the top or side. Enters into a resting state or climbs down.

Wall Scraping- forelegs rapidly beat against the container wall, hind legs attempt to force the cricket higher.

Eating/Drinking- stands on food/wet towel, uses mouth appendages to scrape food/water droplets towards the mouth for consumption.

Jumping- hind legs launch the cricket up and forward.

Jumping/Walking/Climbing onto another cricket- movement onto another cricket. Sometimes a resting state is started or it continues to move about.

Jumping Away- when poked with a pen or container near it is flicked or jostled it uses the hind legs to launch itself in the opposite direction of the disturbance.

Digging- use of forelegs to move sand away to form a hole.

Carrying- picking up and moving food, dead crickets, or scrap paper to another location.

Grooming- moving antennae and legs through mouth using the palps.

Chirping- noise emitted when the males lift their wings and vibrate the abdomen. Pitch and number of chirps varies. Is more frequent at night and when the container is placed somewhere dark.

Antennae Movements- both antennae move about the air space above the cricket, touch the walls of the container or objects within the container.

Antennae Touching- occurs between two crickets when their antennae touch each other.


1. There was an injured cricket that was approached by another, who attempted to drag it away from the wall. Why would a cricket drag another one somewhere else?

2. Do crickets chirp more often when in a warm or cold environment?


1. Crickets are detritivores and will eat their dead.

2. Crickets will chirp more often when placed in an environment that is warmer than room temperature.


1. If a cricket were placed in a warm environment above room temperature then it would chirp more times per five minutes than when in an environment that is colder than room temperature.

2. If a cricket were placed in a cage with a dead cricket then it would consume the dead cricket.

    I like how you separated your ethogram based on if the behavior was an event or state and then explained what each term mean’t. Also be careful when your asking questions that you don’t interpret the behavior, for example for your first question, I would recommend changing it to something like this: Why did the cricket drag away the injured cricket to _____?
    The second question is great and so are your hypothesis’s. Lastly make sure your predictions state a way to be able to measure or count the behavior to further prove your hypothesis! But great job overall.

    What was the result of your prediction? Did the cricket eat the dead? I also liked how specific you were with your predictions, especially how you specified that you would observe the chirps per 5 minutes.

      I was unable to determine if the crickets did eat the dead, my specimen did not survive long enough for the experiment to be run. The primary literature does suggest that it does occur though.
