Conditions:

  • Crickets are kept in my bed room at a temperature around 67-73 degrees. There is moderate noise surrounding them.
  • I will be changing conditions to observe them such as putting them in a different room for a day.

*Photos are my own, taken when crickets first arrived in their new home.

Daily Observations:

1/18/18 6:00 pm

  • I constructed a home with 7 crickets, dog food, carrots, sand, a small house and water. (12:30pm)
  • All moving around when I first put them in the container. Wall scraping, attempted to climb the walls, some are already eating the dog food.
  • Within the 7, I believe I have two adult females and the rest are juveniles that could be male or female
  • The large adult female is staying under the cup and does not seem that curious
  • Some sit on top of one another for a period of time
  • Most of them do not respond to tapping on the container
  • No noise so far

1/19/18 9:00 am

  • Large adult cricket does not seem interested in the others, usually by herself
  • Noise started, it sounds like only one cricket is making noise but several could be doing it at the same time
  • Noise is quieter then I expected, but that could be because of the container masking the sound
  • A few antennas have been broken off from individuals
  • They seem to be eating more of the dog food then carrot
  • When I pick up the container they start running around
  • Looks like one is using its mouth parts like it is cleaning itself

1/20/18 3:00 pm

  • One is on top of another one- mating activity?
  • The juvenile crickets seem to move a lot faster around the container then the larger crickets
  • No noise

1/21/18 1:30 pm

  • Carrots started rotting, replaced them with apples to see change in eating behavior
  • Smallest cricket went right up the apple and started eating it
  • Small little structures almost clear or a yellow color, either eggs or poop
  • 2 other crickets went up to the apple did not eat
  • Taking mouth parts and moving them around head

1/22/18 10:00 am

  • Moved crickets into the living room- wanted to see if change in location changed behavior, also they were loud when I was trying to sleep
  • There was more sunlight in the living room, this seemed to make the crickets go into the house, they also could of been scared from the move
  • Finally all came out of the house except for the adult female, she stayed in the house
  • For about 5 minutes, one cricket tried crawling up the sides to escape, he then proceeded to run around the whole cage, seems like he is stressed being confined in a small scale habitat

Questions

Question 1 : Why do crickets make sounds at certain times and not others?

Hypothesis: Crickets make noise when they are trying to attract a mate

Prediction: If Crickets make noise when they are trying to attract a mate, then the male crickets will chirp showing courtship behavior in hope of finding a mate.

 

Question 2: Why do they move their antennae in different directions?

Hypothesis: Crickets use their antennae as their sensory receptors.

Prediction: If Crickets use their antennae as their sensory receptors, then they move them around to touch and smell the surrounding area.
