Weaving their way

by December 2, 2015 Environment
The next time you visit Lalbagh, keep an eye out for the weavers of the insect world. Here's a look at the fascinating world of weaver ants.

Wildlife surrounds us, and one doesn’t have to go anywhere except to the nearest patch of greenery to observe it.

Last week, I’d been to Lalbagh, and observed the wonder of the Weaver Ants . The scientific name for these ants (not that we need to bother much about it!) is Oecophylla.

Weaver ants, especially the worker ants, make their nests by creating an ‘ant-silk’… Workers construct nests by weaving together leaves using larvalsilk.

But this time, it was unusual to see the ants covering the fruit of the Soursop tree (Annona muricata) for their nests! Perhaps the ants were finding the fruit a ready source of nutrition.

Many studies have shown the efficacy of using weaver ants as natural biocontrol agents against agricultural pests. Apparently, fruits harbouring weaver ants produce better quality fruit!

A surprising fact is that weaver ants are one of the most valued types of insects eaten by humans. This is called entomophagy. In Northeastern Thailand, the price of weaver ant larvae is twice the price of good quality beef!

I also observed the behaviour that the Wiki entry talks about: “Oecophylla workers exhibit social carrying behavior as part of the recruitment process, in which one worker will carry another worker in its mandibles and transport it to a location requiring attention.”

Now that’s really like our ferrying our plumbers or carpenters to our house sites, isn’t it?

I left the busy ants running around on their silken home, and left, musing on the wonders that are there to be seen in every place one looks!

So, the next time you spot a weaver ants’ nest… maybe you could take it home for a crunchy snack… you can bite into it, if you don’t get bitten first!

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

by , , , , and October 8, 2026 Environment
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,…

Bengaluru lakes are changing, and birds are paying the price

by , , , , and October 7, 2026 Environment
From disappearing reedbeds to altered shores, here is why some of the city's lakes are thriving while others face ecological collapse.

While bird detection trends over the years clearly point to the decline of Bengaluru’s shoreline and vegetated-edge habitats, numbers alone tell only part of the story. In Part 3 of this four-part series on the state of the city's waterbirds, we have used a scoring system to understand how stressed the lakes and the microhabitats within the lake are, based on the bird diversity they support. We explore how lake shape, permanent inundation and shifts in citizen-led management might explain why some lakes may thrive as wetlands while others collapse.  For instance, at Kasavanahalli, the Pied Kingfisher and the Coot…
