Read the following text and answer any four questions on the basis of the same :
Ecological Indicators : The presence of dragonflies can reveal changes in the water ecosystems more quickly than studying other animals or plants. In fact, from the nymph to the adult stage, the dragonfly has a significant, positive ecological impact. Dragonfly eggs are laid and hatched in or near water, so their lives show an impact on both water and land ecosystems. Once hatched, dragonfly nymphs can breathe in the air or underwater which enables them to eat mosquito larvae, other aquatic insects and worms, and even small aquatic vertebrates like tadpoles and small fish. Adult dragonflies capture and eat adult mosquitoes.
Community wide mosquito control programs that spray insecticides to kill adult mosquitoes also kill dragonflies.
Q. The most effective stages in the life cycle of dragonfly are eradicating mosquitoes area.
- a)Larvae and adult
- b)Caterpillar and adult
- c)Nymph and adult
- d)Pupa and adult
Correct answer is option 'C'. Can you explain this answer?

Read the following text and answer any four questions on the basis of...
Dragonflies are large and heavy bodied insects. The larvae (or Nymphs), which live in water, eat almost anything living that is smaller than themselves. The adult dragonfly larvae are even known to catch and eat small fish. Usually they eat bloodworms or other aquatic insect larvae. Dragonfly nymphs are such good hunters because they move really fast - by what looks like jet propulsion. One of the benefits of having dragonflies live nearby is that they eat many times their weight in mosquitoes every day. Dragonflies also eat many different kinds of flies. Using a basketlike arrangement of their legs, adult dragonflies can actually catch and eat other bugs while they are flying.

Understanding the Life Cycle of Dragonflies
The dragonfly's life cycle consists of several stages, with the nymph and adult stages being particularly effective in controlling mosquito populations.
Key Stages: Nymph and Adult
- **Nymph Stage**:
- Dragonfly nymphs are aquatic and primarily live in water bodies.
- They can breathe both underwater and above, which allows them to thrive in various aquatic environments.
- Nymphs are voracious predators, consuming mosquito larvae, other aquatic insects, worms, and small aquatic vertebrates like tadpoles and small fish.
- **Adult Stage**:
- Once they mature and transition to the adult stage, dragonflies become agile aerial predators.
- Adult dragonflies feed on adult mosquitoes, significantly reducing their populations in the surrounding area.
Impact on Ecosystems
- **Ecological Balance**:
- The presence of dragonflies is a strong indicator of a healthy aquatic ecosystem.
- Their role in controlling mosquito populations demonstrates their importance in maintaining ecological balance.
- **Response to Insecticide Use**:
- Community-wide mosquito control programs using insecticides can negatively impact dragonfly populations.
- The decline of dragonflies due to such practices can lead to an increase in mosquito populations, undermining the intended purpose of these control measures.
Conclusion
The nymph and adult stages of the dragonfly are crucial for mosquito eradication. Their dual role as predators in both aquatic and aerial environments makes them effective ecological indicators and natural pest controllers.
