How Could Global Warming Affect Monarch Larva?

Abby M

The purpose of my experiment was to see if heat affected the growth of monarch caterpillars. Of all my hypotheses I thought that heat would not have an effect on my caterpillars. To set the experiment up I took eight different containers and placed eight different caterpillars in each container. On the very first day I took measurements of each of the caterpillar so the growth could be measured in length not based on which hatched first. I split the eight caterpillars up into two groups of four, but they were all still in separate containers. Group one was placed in a normal room setting of about 70 degrees Fahrenheit. And group two was placed under a hot setting of 95 degrees Fahrenheit. I measured the caterpillars every day until they formed into a chrysalis. A trend I noticed in the beginning was that the caterpillars under the heated lamp source were growing a lot faster than the ones in the normal setting. My data did not support the hypotheses of thinking heat would not have an effect on the growth because it had a tremendous impact. The group under the heat lamp grew highly faster than the regular temperature caterpillars. I concluded that heat does have an effect on a monarch caterpillar’s growth. I also learned that as the amount of days increased the caterpillars under the heat grew much quicker than a regular heated caterpillar.
