The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Dipteran pupal morphology classification: Obtectate pupae (appendages glued tightly to the body sheath) vs Coarctate pupae (enclosed within a hardened larval puparium cuticle).
Step 2: Detailed Explanation:
Pupal morphological types in Diptera:
1. Obtectate (Obtect) Pupa: The developing wings, legs, and antennae are glued down tightly against the body wall by a hardening secretion. Characteristic of suborder Nematocera, including Family Psychodidae (Sandflies - Phlebotomus), Culicidae (Mosquitoes), and Simuliidae (Blackflies).
2. Coarctate Pupa: The pupa is completely enclosed inside the hardened, barrel-shaped last larval skin (puparium). Characteristic of Cyclorrhapha, including Calliphoridae (Blowflies) and Muscidae (Houseflies).
3. Exarate Pupa: Free appendages (Tabanidae/Brachycera).
Step 3: Final Answer:
Thus, obtectate pupa is characteristic of Psychodidae, matching option (A).
