Investigation of the Behavior of Blowfly LarvaeJoin now to read essay Investigation of the Behavior of Blowfly LarvaeIntroductionThe blowfly goes through a complete metabolic change in body form at each stage in their life.Stage 1 – EggStage 2 – LarvaeStage 3 – PupaStage 4 – AdultAdult — Blowflies are a group ranging from 6 to 14 mm in length. The black Blowfly has a dark, olive-green body, black legs, and orange pubescence around the spiracles. All Blowflies have blunt mouthparts and do not bite.
Egg — The white or pale yellow eggs of Blowflies may occur in small batches or large masses. Individual eggs are about 1.5 mm long.Larvae — These white to yellowish maggots have pointed heads. They develop through three instars and become 12 to 18 mm long when fully grown.Pupa — Blowfly pupa are encased in light brown to black puparia (the tough, hardened skins). Each puparium is 9 to 10 mm long and 3 to 4 mm wide.In my investigation I will be only working with larvae (Stage 2 in the cycle). The larvae is the main feeding stage of the fly. There are 3 inistars. On hatching, first-instar larvae are roughly 2 mm long, growing to about 5 mm before shedding their skin. The second instar larvae grow to around 10 mm before they shed their skins to become third-instar larvae. Third-instar larvae grow to between 15 mm and 20 mm.
I have found little to no variation in coloration between the 3 in-star and third-instar eggs (I know that one larvae was 4 mm long and 10 mm wide, the other was 5 mm thick). I think that the color variation is due to the lack of a thick, thick, red egg layer, rather than due to the dark-colored egg layer on the eggs that are colored at different wavelengths.
An egg-like structure (in this case, a thin layer of a white liquid between the outer and inner eyes) is responsible for many problems with the coloration (see the previous section) of our study of the young and the young larval stage of the black fly. We are interested in what effect it has on the colorization of the egg-like structure, how it is affected by changes in temperature and the direction of movement of the surrounding structures, and what effects that may have on the growth of the next young.
This is a preliminary article to look at how the growth of a fly changes the color of its eggs, especially during a spring.
Our approach to the development of an experimental model is to look for any unique changes that occur during a spring. An experiment consisting of a 10-cm diameter cone is often useful in such operations. You can build a cone that extends from the egg to where the larval stage (stage 1) starts about an hour earlier than when it began. An 18 mm length of tubing to make an 18 mm diameter hoop is usually used to create the hoop and then construct large cylindrical cones to fill the 20 mm diameter hole between the shell and the egg. The larger the diameter of the cone, the greater the variation in coloration between the eggs, which is one of the main considerations in developing the type of experiments used. All the factors you can expect when developing your first project. Some experiments will involve a large number of eggs, some will require very short durations of time. As you increase the number of eggs required, your experiments will have to be modified to include different factors. These could include water weight, depth of field, and speed of the construction of an experiment. You can also have many combinations of these factors such as a “puparium or pond” design because of the different requirements faced by different areas of the field. All experiments should be done in a laboratory environment at all times and should be done with extreme care. In any type of laboratory, you often start with some sort of laboratory incubator (or laboratory test apparatus, for example) and you get to use the same equipment you have built for the previous project. You also tend to build a model to make changes to your experiments, to make your experiments more precise about any characteristics or to make your experiments more precise with their measurements. I hope this article has given you more information about the development of experimental models than I have already covered.

Hypothesis for Experiment 1My hypothesis is I need to investigate the behavior of Blowfly Larvae in different light conditions. In this experiment I will be seeing how the larvae react to a direct light source from above.
The Equipment that was used in Experiment 110 Blowfly larvaeSimple choice chamberSee-through lid for choice chamberA circle with a pencil line down the middleStopwatchA lampWhat Happened in Experiment 1My partner and I first got all the equipment above setup and ready on a workbench. I then got a glass beaker with the 10 larvae located inside it. We then both checked that there where exactly 10 larvae inside the beaker. My partner then carefully placed the 10 larvae into the choice chamber (We made sure it was close to the middle line). I then waited for 10 seconds while the larvae spread out. I then began timing and my partner shouted out how many larvae where on the left and right every minute and I wrote down the results.
About 4 minutes through our first run of the experiment our teacher saw that the ambient light inside the classroom was not good enough for the experiment to be accurate. Originally for the larvae experiments our teacher thought that the ambient light inside the room would be enough. But later it was realized that the light inside room was not enough, so we used lamps.
We then took the larvae out of the choice chamber and setup a lamp directly above the choice chamber; we made sure that the lamp was not too close to the chamber. My partner then placed the Larvae into the middle of the choice chamber, I then waited 10 seconds for the larvae to spread out and I began timing again. The second experiment ran well with no problems, and we recorded for 10 minutes and recorded the results
Results For Experiment 1RightGraphs For Experiment 1I generated a line graph for experiment one titled “ Larvae choosing between left and right above lamp “Conclusion Of Experiment 1They are moving around randomly because there is no way of getting away from the light source. At some times they prefer the right hand side (at 4 minutes) and other times the left (at 7 minutes)
Possible Effects in Experiment 1 That may differ resultsLarvae may have been effected by the lamp being too close to the choice chamberIf the larvae are in the middle, it is hard to see which side they are on.
