What characteristic of mosquito mouthparts contributes to the lack of pain when they bite?
What characteristic of mosquito mouthparts contributes to the lack of pain when they bite?
- They inject an anesthetic while biting.
- They are coated in a smooth substance.
- They have serrations that reduce nerve contact. (correct)
- They have a wide diameter.
Why is the painlessness of mosquito bites crucial for their survival?
Why is the painlessness of mosquito bites crucial for their survival?
- It prevents them from being detected by their hosts.
- It allows them to feed without interruption. (correct)
- It helps them to reproduce faster.
- It reduces competition from other insects.

Study Notes
Biomimicry and Painless Needles
- Biomimicry, the process of using nature's designs to solve human problems, can create medical tools like painless needles.
- Mosquito bites are painless, providing a potential model for creating needles that do not hurt.
- Mosquitoes have thin, sharp mouths shaped like tiny needles, as thin as a human hair, minimizing nerve stimulation.
- The needle-like mouths of mosquitoes have small, saw-like edges (serrations), making contact with only a few points on the skin, further reducing pain.
- The lack of pain associated with mosquito bites is crucial for their survival. If they caused as much pain as injections, their survival rate would likely be reduced.
- Research on the structure of mosquito mouths is informing the design of new needles to reduce pain during injections.
- These new, pain-free needles are already in use in some contexts and may become commonplace in the future.
