Question

the larva and the pupa represent two stages of an insects life. after an egg hatches, an insect enters the first active phase of life and becomes a larva. the larvas main job is to feed and store energy. the pupa is the next stage of an insects life. although the larva feeds constantly, the pupa usually does not feed and appears motionless. unless it lives inside a stem or a leaf, the pupa builds a protective outer shell called a cocoon. inside the cocoon, the pupa transforms from a soft, worm - like creature into a new physical form, such as a butterfly or a moth. unlike the pupa, a larva doesnt build a cocoon and remain inside. instead, the larva is busy eating—and often destroying—agricultural crops.

Explanation:

• For "Is in the first active stage of life": The text says "After an egg hatches, an insect enters the first active phase of life and becomes a larva", so this is for a larva.
• For "Doesn't feed": The text states "Although the larva feeds constantly, the pupa usually does not feed", so this is for a pupa.
• For "Is usually enclosed in a cocoon": The text mentions "the pupa builds a protective outer shell called a cocoon", so this is for a pupa.
• For "Can damage crops": The text says "the larva is busy eating—and often destroying—agricultural crops", so this is for a larva.

Answer:

• Is in the first active stage of life: A larva
• Doesn't feed: A pupa
• Is usually enclosed in a cocoon: A pupa
• Can damage crops: A larva
