Summary Introduction

To explain: 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.
