Question

Antennae shorter than body and consist less than 30 segments are:

• A. Tridactyloidea
• B. Tettigonioidea
• C. Acridoidea
• D. Grylloacridoidea

Hint:

Remember the classic Orthopteran split:
- Caelifera (e.g., Acrididae/Acridoidea) = Short-horned grasshoppers (antennae $<$ 30 segments).
- Ensifera (e.g., Tettigoniidae) = Long-horned grasshoppers/crickets (antennae $>$ 30 segments).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The order Orthoptera (grasshoppers, crickets, and locusts) is divided into two distinct suborders based on the length of their antennae and the number of antennal segments.

Step 2: Detailed Explanation:
- Suborder Caelifera (short-horned grasshoppers, including the superfamily Acridoidea): Characterized by short antennae (much shorter than the body length) composed of fewer than 30 segments.
- Suborder Ensifera (long-horned grasshoppers and crickets, including Tettigonioidea and Grylloacridoidea): Characterized by thin, thread-like antennae that are longer than the body and consist of more than 30 segments.

Step 3: Final Answer:
Antennae shorter than the body with less than 30 segments belong to Acridoidea, which is option (C).
