Entomology

Step 1: Recall the complete metamorphosis cycle of insects like mosquitoes. Step 1: Mosquitoes undergo complete metamorphosis, which means their life cycle has four distinct stages.
Step 2: List the stages in their natural order.
Step 2:

(C) Egg: The life cycle begins when a female mosquito lays eggs on or near water.
(B) Larva: The eggs hatch into larvae (often called "wrigglers"), which live in the water and breathe at the surface.
(D) Pupa: The larva develops into a pupa (often called a "tumbler"), which also lives in the water but does not feed.
(A) Adult: The adult mosquito emerges from the pupal case and flies off.
Step 3: Form the correct sequence.
Step 3: The correct life cycle sequence is Egg Larva Pupa Adult, which corresponds to C B D A.
