Question

Chewing and biting type of mouthparts are also known as:

• A. Sponging Type
• B. Chewing and lapping type
• C. Sponging type
• D. Mandibulate Type

Hint:

Chewing and lapping mouthparts allow insects to perform both solid food biting and liquid food lapping.

Answer 1

The Correct Option is B

The chewing and lapping type mouthparts are characterized by:
Combination of mandibulate and lapping adaptations
Example: Honeybee, which can chew wax and also lap nectar
Different from pure mandibulate (biting
chewing) or sponging types

Answer 2

Reasoning from mouthpart modification:
In this type, the mandibles remain largely unmodified and retain their original biting and chewing function, while the labium is separately modified into a flexible, brush-tipped "tongue" used to lap up liquids such as nectar.
This partial modification, chewing structures retained plus a lapping addition, distinguishes it from the purely biting-chewing (mandibulate) type and from the fully modified sponging type seen in houseflies.
The honeybee is the classic example, chewing wax and pollen with its mandibles while lapping nectar with its glossa, which is why this combination is named the chewing and lapping type.
