The correct option is 1 and 3 only.
Explanation
The Wildlife (Protection) Act, 1972 (WPA) provides the legal framework for the protection of various species of wild animals and plants. While initially focused on larger vertebrates, the scope of the Act was subsequently expanded to include invertebrates such as insects.
- Statement 1 is Correct: When the Wildlife (Protection) Act was enacted in 1972, it did not include insects. Insects were brought under the purview of the Act for the first time through a notification in 1980, which added several species of butterflies, moths, and beetles to the protected schedules.
- Statement 2 is Incorrect: Dragonflies are not explicitly excluded from protection. Specific species of dragonflies, such as Epiophlebia laidlawi, are listed under Schedule I of the Wildlife (Protection) Act, granting them the highest level of legal protection.
- Statement 3 is Correct: A wide variety of butterflies (e.g., Kaiser-i-Hind) and beetles are included in the protected lists (Schedules) of the WPA. They are categorized under different schedules based on their conservation status and threat levels.
Key Takeaway: The Wildlife (Protection) Act, 1972 extends protection to insects, including specific species of butterflies, beetles, and dragonflies, which were primarily introduced into the schedules via the 1980 amendment/notification.
