Butterfly journeys

It's that time of the year when the Blue Tiger makes its way to the Western Ghats. Keep your peeled for these butterflies as they flit past you when you are out and about.

We witness a beautiful aerial stream of butterflies between March and May, and once again between September and November. These butterflies are not, like other wildlife, only to be found in the forests; you can often see them floating around you, and past you, as you walk in the city. 

The most common butterflies that migrate twice a year are the Blue Tiger, and the Common Crow. The Common Crow is a dark brown, almost black butterfly; but the Blue Tiger is a blue jewel! 

You can see them clustering on some plants even in uncultivated fields.

The butterflies migrate to the Western Ghats to breed, and it’s amazing to think that it’s the progeny who return. 

Several thousand butterflies, of course, fail to complete the journey, and become food for predators, or decompose back into nature, thus completing the cycle of life and death.  

Here’s a video I took, of Blue Tigers flickering in large numbers as they fly about an open area. 

Another interesting fact is that the scientific name of these butterflies is ‘Tirumala‘… A tip of the hat to the Lord of the Seven Hills. 

So look around and notice the winged travellers as you walk around our city at this time!

Explained: How Mumbai is losing its tree cover to infrastructure projects

Mumbai's landscape is changing with big infra projects. Experts suggest better use of government plots and improved street design to retain green cover.

Long before Mumbai’s relentless summer even began this year, the city was already simmering. In March, Mumbai was hit by a severe heatwave, with the temperature reaching a five-year high of 40° Celsius. As rapid urbanisation and a flurry of infrastructure projects replace dense tree cover with steel and mortar, heatwaves seem to have gone from being rare occurrences to an annual threat.   The Mumbai Metro Rail Corporation Limited (MMRCL) cut a whopping 3,093 trees in Aarey Colony to make way for Mumbai’s Aqua Line ( Metro 3). For environmentalist Stalin Dayanand, this is not just a temporary problem.…

Notes from the field: Why Begur Lake is losing its waterbirds

71% of waterbirds at Begur Lake are declining. A visit to one of Bengaluru’s rapidly deteriorating lakes shows what's causing the collapse.

During the Open City biodiversity datajam held in December 2025, our group examined the ecological trends around Bengaluru’s lakes. Our analysis suggests a majority of waterbirds are declining across the city's lakes. Earlier, we addressed crucial questions on how migrant and resident waterbirds are surviving across 14 of Bengaluru’s lakes, how the shape of the lakes influence microhabitats, and how a scoring system can be used to record the decline in lake quality and bird populations. The last of our four-part series turns its attention to an individual site. As part of this study of waterbirds in 14 city lakes,…
