Step 1: Understanding the Concept:
Many insect orders are commonly referred to by the vernacular names of their best-known representatives.
Detailed Explanation:
Let us match each insect order with its common representative:
- (A) Plecoptera: These are hemimetabolous insects with aquatic nymphs that require clean, oxygen-rich environments. They are commonly known as Stoneflies (I).
- (B) Mecoptera: The males in this group have terminal abdominal segments curved upward like a scorpion's stinger. They are commonly known as Scorpionflies (II).
- (C) Neuroptera: This order contains predatory insects with net-veined wings, including green lacewings and Antlions (IV).
- (D) Dermaptera: These insects have short, leathery forewings (tegmina) and posterior forcep-like cerci used for defense and grooming. They are commonly known as Earwigs (III).
This gives the match: (A) - (I), (B) - (II), (C) - (IV), (D) - (III).
Step 2: Final Answer:
The matching sequence corresponds to option (3).
