History for larva
To biologists in the 1700s, the adult was the only genuine form of an insect. The stages that come between the egg and the adult in many insects' lives were considered somehow unreal, or at best disguises. These stages were named with the Latin words pupa, “doll,” and larva, which in the Latin of the ancient Romans was a sort of ghostly demon or a mask representing a demon. Although to modern biologists larvae such as caterpillars are as real as adults, the traditional terms larva and pupa remain with us.
