Question

'Siphoning' type mouth parts are seen in:

• A. Cockroach
• B. Butterfly
• C. Honeybee
• D. Silverfish

Answer 1

The correct option is B Butterfly

• The insects having siphoning mouth parts that do not chew their food but suck or siphon the nectar (food) through the siphoning mouthparts.
• Moths and butterflies have siphoning mouthparts that are adapted to draw nectar from long-throated flowers.
• Unlike piercing-sucking mouthparts, these do not penetrate into the plant.
• This feeding is analogous to inserting a straw into a drink to withdraw liquid.
• The proboscis is held coiled under the head when not in use. During feeding, however, it is extended to reach the nectar of flowers.

Therefore, the correct answer is option B.
