Would someone help me with my science fair project?

Ok, for a science fair project I did the light color preferences of crickets. I now have to explain my results and I cant find the reason for some of them.

What I found after averaging everything together, was that yellow was the most popular color, red was second, and blue was last. Any idea why it was yellow? You would think they would choose blue, because it most replicates night, which is when they come out

Also, on the side, I found that they were most active in red. More often the crickets in red were hopping around and eating. In all the other sections, the crickets mostly just sat there, sometimes on the sponge. Another interesting thing I found that I would find more in yellow that were dead, where as most the times none were dead in blue.

Any reasons for these?Would someone help me with my science fair project?
It might be that yellow is the closest color to the surrounding plants, so they use that color to hide them. (Why they don't

use green is beyond me, maybe it's too TIRING to make...).





Anyway, why did they die? I'm gonna go out on a limb and

say that they are the most timid, they find it hard to make adjustments, and are not well suited to survive. (Malnourished?).





We will see in the future.Would someone help me with my science fair project?
ummmmmmm. Maby they are just stupid.i truely have no ida.Many people recognize crickets without even seeing them. They identify the familiar chirping sound made by the male cricket in his efforts to attract a mate. The sound is most often heard at night when crickets are most active, prowling about looking for food, moisture, and a consort.



Crickets undergo simple, or incomplete, metamorphosis; they molt several times as they grow, each molt revealing larger, more fully developed crickets, until the last molt results in adults.



The female cricket has a structure protruding from the rear of her abdomen that students often think is a long stinger. It is an ovipositor, which the female thrusts into moist earth in order to lay her eggs well below the surface. When the eggs hatch, the nymphs dig to the surface, where they fend for themselves.



Crickets have other interesting features, starting with a pair of spikes that extend out from the end of the abdomen in both sexes. The cricket has two pairs of wings, the front two of which are equipped with rasplike adaptations that, when scraped together, produce the chirp. The hindmost pair of legs are greatly enlarged, allowing the cricket to spring huge distances when motivated by alarm or other stimuli. On the frontmost pair of legs are membranes that are sensitive to sound vibrations, so in effect the cricket has its ears on its legs. The antennae are long, lithe, and sensitive. It is fascinating to see the exquisite control the cricket has over these wispy structures as it probes and feels its environment before rushing in.



The cricket most used for classroom cultures is the house cricket. It lives in containers quite well and is content to eat seeds, fruit, grass, and dry dog food. However, crickets are good at escaping confinement. They will gnaw through paper or cardboard quite quickly, and if they are overcrowded, hungry, or thirsty, they will chew through nylon mesh covering a cricket container. For this reason it is necessary to cover the container with metal screen.



Cricket habitat. The FOSS cricket habitat has three chambers. One contains soil that is kept moist. This is where the females will lay eggs. A second chamber contains dry sand. Food should be placed in this area so that it will not mold. The central area is the exercise yard with structures for climbing and hiding.



Crickets need paper, sand, or soil to get around because their feet are not adapted for holding onto smooth surfaces. A large or complex cricket culture container will allow the crickets to display preference for variables such as moisture, temperature, and structure. Crickets prefer a hot, dry environment. If they are kept in a humid environment, they can develop a fungus, so lots of ventilation is needed. They can go into a moist environment to eat or lay eggs, but they must be able to retreat to dry ground. If you like, you can train a lamp on the central part of the habitat鈥攖he crickets will congregate there to bask. And you will probably get a song tossed in as part of the bargain.
