Show Hint
Remember the parts of the Maxilla:
Cardo + Stipes + Lacinia + Galea + Palp.
The galea is particularly famous because it evolves to form the siphoning tube of butterflies.

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Detailed knowledge of the sub-components of insect mouthparts is essential for understanding feeding adaptations and evolutionary modifications (e.g., siphoning tubes).
Step 2: Detailed Explanation:
The first maxilla (paired mouthpart) is structurally complex and consists of:
- Cardo: The basal segment that articulates with the head capsule.
- Stipes: The middle segment.
- Lacinia: An inner, tooth-like chewing lobe.
- Galea: An outer, scoop-like sensory lobe.
- Maxillary palp: A segmented sensory appendage.
In adult Lepidopterans, the two galeae are enormously elongated and lock together to form the long, coiled siphoning proboscis.
Step 3: Final Answer:
Galea is a structural part of the Maxilla, which corresponds to option (B).
