Butterflies and Moths, Size Comparison
Sara C, Abbey W
We caught four butterflies and four moths and measured their body length and wingspan to determine their average size. The purpose of this experiment is to see if on average if butterflies or moths are larger. The results of our experiment were that moths are larger than butterflies, but not by much. There were many uncertainties during our project. The uncertainties were the weather and time of year. It was cold and windy while we were looking for them, so that may have influenced how many butterflies were out flying around, resulting in a small sample size. Two new things we learned were that moths are larger than butterflies, and that, in October, it’s a lot harder to catch butterflies than moths.
My project on Entomology has a lot of history starting with cave drawings from 13,000 years ago to new advances in the insect research in the 21st Century. Many people are noted in the study of entomology and many are called the ‘founder’ of this subject like Maria S. Merian and also Pietro Rossi. There is a weird coincidence, 3 entomologists were born in the same year and they all studied the same thing diptera. Some other achievements that changed the world is that only 109 years ago, that mosquitos can transmit malaria by biting the person.
We tried this experiment four tries; two out of the four times the scorpion reacted to our presence, so the other tries meant that the scorpion just sat there. We learned that some scorpions, do not get used to stuff that easily as we thought, but I guess that’s not right for scorpions, maybe even insects. We also learned one more thing that scorpions aren’t as viscous as we think they are, usually people think that being around a scorpion they will attack.
