The behavior of a caterpillar during early spring to maintain thermoregulation. Concept introduction: Thermoregulation is the ability of an animal to maintain its body temperature within an acceptable range with respect to external temperature. Thermoregulation mainly depends on an organism’s capacity to control the exchange of heat with its environment. There are two forms of animals through which they maintain thermoregulation; they are ectotherms and endotherms. Endotherm get warmed mostly by heat generated through metabolism . Ectotherm means that they absorb most of their body heat from the external sources.

Eastern tent caterpillars (Malacosoma americanum) live in large groups in silk nests resembling tents, which they build in trees. They are among the first insects to be active in early spring, when daily temperature fluctuates from freezing to very hot. Over the course of a day, they display striking differences in behavior: Early in the morning, they rest in a tightly packed group on the tent’s east-facing surface. In midafternoon, they are on its undersurface, each caterpillar hanging by a few of its legs. Propose a hypothesis to explain this behavior. How could you test it?

Monarch butterflies are commonly found throughout the bulk of the United States during most of the year, but primarily spend the winter months in central Mexico. The butterflies can tolerate temperatures as low as about 40 degrees Fahrenheit, unless conditions are also rainy. Under wet conditions, the butterflies require warmer temperatures in order to maintain their body temperature. The butterflies spend the winter roosting in large clusters that hang from mature conifer trees. This clustering helps the butterflies maintain their body temperature, and avoids the dangers of roosting on the ground, where they might be susceptible to danger. Consequently, the butterflies can only overwinter in areas with mature trees, which have been reduced throughout the area due to logging. Which of the following statements are true of the monarch butterflies’ overwintering niche? (Select all that apply) A. The butterfly’s realized niche includes regions with lower temperature and precipitation…
