Blue Earthworms Mass Migrating in Meghalaya

23 February 2021 Current Affairs:The Zoological Survey of India (ZSI) has compiled a report on the two-way spread of the blue earthworms in Meghalaya. Highlights: ♦ The 1.6-foot-long blue earth migrates up or down to 300 meters on the East Cassie Hills in the state. ♦ April’s uphill migration started from April to May. As the monsoon erupts, they emerge from rivers and streams. ♦ Downhill migration occurs from September to October, when vegetation begins to dry out and temperature and humidity drop. ♦ Locals in the state beat them while observing these earths because they play an important role in enhancing soil fertility. ♦ In addition, it helps to enable local people to switch to ecologically sustainable organic agriculture. ♦ In some areas of the state, unsustainable land use practices have greatly reduced the number of the earthworms. The damage was mainly caused by quarrying and heavy soil logging. ♦ Various factors including development activities, unstable weather patterns, predation and climate change have led to the large-scale migration. ♦ The scientific name of blue earth is Perionyx. It is also called Compost Worm, Blues or Indian Blues. This species is known for being able to make high-quality worm castings so quickly. This species has recently become popular in North America for composting. Scientists believe that its origin is in the Himalayas. It is also suitable for vermi composting in tropical and subtropical regions.
