I often come across the Balloon Vine (also called "Love in a puff") on my walks through the fields and forests around my city. It's a very common vine, indeed....and in fact, in New Zealand, it is identified as a prohibited pest plant! However, in Kerala, the flower of this vine  is one of the ten "sacred flowers" Seed pod and flowers: I found that the scientific name for the genus of this vine is "Cardiospermum". The name intrigued me, until a friend and avid amateur botanist, Ajit Ampalakkad, showed me the seeds inside the "balloons". Each seed was attached to the…

There's no denying that butterflies bring touches of bright colour to a dull, rainy day. At the Valley School near Bengaluru, on Gandhi Jayanti, (2 October 2017) we were singing the Blues.... Blues are Lyacaenid butterflies, which show a bright blue colour when flying (and which is often hidden when they alight and fold their wings.)  As Wikipedia puts it, Lyacaenidae is the second-largest family of butterflies (behind Nymphalidae, brush-footed butterflies), with over 6,000 species worldwide, whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species. Some species among them are known to be…

The third week of August ended with a wildlife event and a wildlife/conservation festival, both of which I thoroughly enjoyed. The first was the screening of "Cobra King", a documentary on the King Cobra made by Sandesh Kadur of Felis Creations It was Gowrishankar of Kalinga Centre for Rainforest Ecology narrating the life cycle of this iconic reptile of the Western Ghats. I cannot yet find the documentary on the net ( has it not yet been released to the wild, like rescued snakes are...?), but here is another video on the same snake from the same film maker: Here's…

For some time, there was a debate about which butterfly should represent Karnataka. The State has a record of about 318 species of butterflies, and the choice of butterfly had to be one which would be the most representative of the State.  The proposal to adopt the  Southern Birdwing  as the State butterfly had been sent by Sanjay Mohan, Additional Principal Chief Conservator of Forests (Research and Utilisation). A few butterflies had been shortlisted, including the Common Jezebel, but the Southern Birdwing was finally chosen, as its colours match those of the Karnataka flag. Maharashtra had chosen the Blue Mormon…

Many of us have small gardens or even potted plants at home, to add a touch of greenery and, as we hope, to purify the city air.  Houseplants play several beneficial roles in our home environment. They provide visual interest to the home, purify the air, and may be edible or medicinal. What many of us may not know, however, is that some of these plants can be poisonous! Toxic plants can be a hazard to children and pets, as well as to elderly persons with dementia. Though  it would be better  to keep all plants out of the reach…

I saw this beautiful moth on the staircase of my apartment building,  day before yesterday.... I called it the military camouflage moth, but the correct name for this is the Oleander Hawk Moth, in the Sphinx moth family Sphingidae. The scientific name of the moth is Daphnus nerii. Military camouflage moth was simpler, perhaps? The caterpillar of this Moth, like that of many others, has several "instars" or forms. Here's one: The head of the caterpillar is actually towards the right...the "eyes" are probably to fool a possible predator with that appearance of fierceness. These caterpillars actually feed on the Oleander…

Sights and sounds at Yediyur Lake I am not immune to FB posts, so when there was a sudden rush of bird sightings from Yediyur kere, I realized that I'd not visited for many years. When Padma and Ramaswamy suggested going there this morning, I was very happy to join them. So many trees have fresh leaves right now, like this Peepal tree: This lake is maintained well. However, the fact of its being completely fenced around, and having all growth stunted to bush size except for a few spots, made it feel more "manicured" than I am comfortable with...but…

Several blooms to delight the senses! A walk in Lalbagh is always something that will bring a lot of joy. I decided to capture some of the blossoms that appealed to my eyes, my nose, my touch, and sometimes, as they rustled in the morning breeze, to my ears, too! Some of them are quite uncommon trees that I have not yet seen outside the park. The Purple Bauhinia (Bauhinia blakena) and the Cabbage Bark Tree (Andira inermis) can be seen in the garden. These are the flowers of the Cabbage Bark Tree (Andira inermis). Pic: Deepa Mohan The beauty…

Pic: Deepa Mohan I've always been drawn to owls. The Rock Eagle Owl, also called the Indian Eagle Owl, has been one of my favourites; I've sighted it at Bannerghatta, Turahalli, and at various other locations. For the past few years, we've been watching some of these majestic birds making their homes on the rocky outcrops of the highway built by Nandi Infrastructure Corridor Enterprises (NICE), around Bangalore. As we were returning from our trip to Sakleshpur, where we did a bird census for a coffee estate (a very satisfying assignment, more about it later!) we decided we would detour…

On Dec. 23, 2016, I conducted a “Walk-n-Talk” for the residents of the campus at Indian Institute of Managament, Bangalore (IIMB). Pic: Deepa Mohan Prof Shainesh, who is the Dean of Administration, and a keen birder himself, opened up the campus for two bird census events in Feb and Nov 2016, and he wanted to ensure that the residents on the campus also got to know more about the flora and avifauna in the place where they live. Group before setting off for the walk. Pic: Deepa Mohan Dr. Selvarajan Rajeswaran, who is doing a doctoral program at IIMB, was…
