- New Damselfly Species Discovered: Euphaea wayanadensis, a new damselfly species, has been identified in the Wayanad region of the Western Ghats, Kerala.
- Significance for Kerala & Western Ghats: The discovery brings Kerala’s recorded odonate (damselfly and dragonfly) species count to 191 and the Western Ghats’ total to 223.
- Published Research: The findings were published in the journal ENTOMON.
- Initial Misidentification: The species was initially mistaken for Euphaea pseudodispar. Detailed study and genetic analysis confirmed its unique identity.
- Distinguishing Features: Key morphological differences include a longer black patch on the hind wing, broader humeral and antehumeral stripes in males, and a unique male genital structure.
- Habitat Preference: Euphaea wayanadensis thrives in fast-flowing streams with rocky beds and aquatic vegetation within evergreen and semi-evergreen forests.
- Restricted Distribution & Vulnerability: The species has a highly restricted distribution, making it vulnerable to habitat loss and climate change. It is active year-round, except during the dry seasons.
- Ecological Importance: Damselflies, including Euphaea wayanadensis, serve as indicators of freshwater ecosystem health due to their sensitivity to water pollution.
- Discovery Location: First observed in the Kalindi River, Thirunelli, Wayanad, Kerala. Later sightings occurred in Aralam (Kannur, Kerala) and Coorg (Karnataka).
Great Red Spot
-
New Observations: Jupiter’s atmosphere around the Great Red Spot is surprisingly active and interesting.
-
What it is: The Great Red Spot is a long-lasting anticyclone (high-pressure area) on Jupiter, creating a persistent storm.
-
Location: Southern Hemisphere of Jupiter.
-
Appearance: A giant red spot. The cause of the red color is unknown.
-
Size: Diameter of 15,400 miles, almost twice the size of Earth and one-sixth the diameter of Jupiter.
-
Wind Speed: Winds inside the storm reach speeds of about 270 mph.
-
Lifespan: It has existed for at least 150 years, possibly longer.
-
Why it lasts: Jupiter’s lack of
a solid surface allows the storm to persist. A solid surface would dissipate the storm’s energy. -
Changes: The Great Red Spot changes in shape, size, and color.
-
Largest Storm: It is the largest known storm in the Solar System.
AFSPA Extension in Northeast States
- AFSPA Extension: The Central government has extended the ‘disturbed area’ status under the Armed Forces (Special Powers) Act (AFSPA), 1958 in parts of Northeast India.
- Manipur: AFSPA extended in Manipur, excluding areas under 13 police stations in five districts, for another six months.
- Nagaland & Arunachal Pradesh: AFSPA extended in parts of Nagaland and Arunachal Pradesh until 30th September 2025.
- Reason for AFSPA: The Act was originally implemented in 1958 to address escalating violence in the Northeast that state governments couldn’t control.
- Powers Granted: AFSPA grants armed forces personnel in “disturbed areas” special powers, including the authority to use force (even lethal), arrest without warrant, and conduct searches without warrant.
- Protection from Prosecution: Armed forces personnel are protected from legal proceedings for actions taken under AFSPA without prior sanction from the Central Government.
