What are the larval forms of butterflies or moths commonly referred to as?

The larval forms of butterflies or moths are specifically referred to as caterpillars. This terminology is widely accepted in entomology and is used to distinguish them from other insect larvae or developmental stages. Caterpillars are the primary feeding stage for these insects, and they often exhibit a distinct body shape and movement compared to other larvae. Understanding this term is essential for those studying insect life cycles, particularly with regard to pest management and ecological impacts.

In contrast, while larvae is a general term for the immature form of many insects, it does not specify the type of insect, thus lacking the exactness required in this context. The term worms commonly refers to various non-insect organisms and can lead to confusion when discussing caterpillars. Pupae represents an entirely different stage in the insect life cycle, being the transitional stage between larva and adult, and not the larval form itself. Therefore, recognizing caterpillars as the correct and specific term is crucial for accurate communication in entomological discussions.
