Use 'pupa' when discussing biology or the life cycles of insects, such as in science class.

Context: Biology

'Pupa' often refers to a stage where the insect is enclosed and hidden, as in a cocoon.

Not Always Visible

The word 'pupa' signifies transformation, where the larva changes into an adult insect.
