What is a pupa?

Definition of pupa : an intermediate usually quiescent stage of a metamorphic insect (such as a bee, moth, or beetle) that occurs between the larva and the imago, is usually enclosed in a cocoon or protective covering, and undergoes internal changes by which larval structures are replaced by those typical of the imago.

• Stage 2: Larva. Almost all insect species go through larval stages.
• Stage 3: Pupa.
• Stage 4: Adulthood.

– Exarate pupa – appendages are free and are not usually encapsulated within a cocoon. All decticous pupa and some adecticous pupa are always exarate. – Obtect pupa – appendages are attached closely to the body and are commonly encapsulated within a cocoon. – Coarctate pupa – enclosed in a hardened cuticle of the penultimate larval instar called puparium.
