Butterfly List

Photos: Not just pretty pictures, a new butterfly catalogue can help save India’s rivers

Keeping track of butterflies at headwaters of rivers can help track the health of forests and their water bodies

India finally has its first comprehensive catalogue of butterflies since Independence. Peter Smetacek, a scientist at the Butterfly Research Centre at Bhimtal, spent years putting together a synoptic list of the 1,318 species found across the country. The exercise is not only to document the variety of butterflies in India but to help save India’s rivers – a cause that Smetacek has been championing.

“We have been trying to analywe the health of the forest using the insect community there and that is why the catalogue is important because you must know what is where,” Smetacek explained. To do this, scientists first must clarify taxonomy of the various species and then ascertain what a forest contains. “We did that with butterflies and we will move on to moths," he said. "In due course we will have a map of different types of community structures in different parts of India, especially in the headwaters of rivers.”

The eventual goal, the butterfly expert said, is to charge forest departments with maintaining or monitoring populations of insects, birds or other bio-indicators that tell us about the health of the forest at headwaters. Acting on the basis of such ecological information, experts could act to stabilise the flow of rivers so that it can really ensure our water security.

“That is the only concrete approach. All the rest that we are doing with dams and so on are of no use,” said Smetacek.

Butterflies may not be the best plant pollinators around but they are integral to the food chain, converting plant matter to animal protein by serving on the diets of insects, frogs, wasps and birds. The new catalogue has been the first butterfly list compiled for India since 1932. After Independence and Partition, no one knew which butterfly species remained in Pakistan and the occupied parts of Kashmir. The Synoptic Catalogue of the Butterflies of India that has been edited by Smetacek and RK Varshney, retired additional director of the Zoological Society of India, has filled in those information gaps.The catalogue includes remarkable varieties like the Travancore Evening Brown, a butterfly endemic to India and found only in Kerala and Karnataka. The butterfly is the only existing species in its genus and its closest relative is found in South America indicating that its belongs to a lineage that went extinct ages ago. “Luckily there is a very good, viable population in protected areas,” said Smetacek.

Here's a look at some of those 1,318 species.


Bronze Duke Euthalia nara found in the Eastern Himalaya.



Indian Fritillary male found over most of India.



Orange Oakleaf Kallima inachus found in northern India is the best example of camouflage.



Striped Blue Crow Euploea mulciber has brilliant blue marking and slow, unhurried flight.



Tailed Punch Dodona has a false head at the tip of the hindwing.



Tiger Brown Orinoma damaris is the only species of its genus found from Himachal Pradesh to China.

Inspiration for the lazy, the casual and the gourmet home chefs alike

Discover, or rediscover the daily delight in food, one ingredient at a time.

It is known that home chefs can be arranged in a pyramid - the lazy ones at the bottom, the casual cooks in the middle and the gourmet experts at the top. While the challenges differ with each level, great solutions exist to make every meal an experience, regardless of the kind of cook you are. This guide to creating delightful food has something for everyone.

The lazy, hassled home chefs

You can ease into cooking by putting together meals that require minimal technique. Salads are a good place to start. Experiment with seasonal and exotic fruits and vegetables, tender vegetables and herbs, and artisanal breads as sides for a fresh, healthy and surprisingly gourmet experience.

Don’t be dismayed if you’re a non-vegetarian. There are still meals that require next-to-no prep. Think sausages that can easily be fried or grilled and cold cuts that pack a flavour punch. Health-conscious people can look for additive-free, preservative-free meat, bromate free bread and produce from free-range farms for assurance of quality. For variety, you can even put together a great Middle Eastern platter with fresh hummus and other dips.

For the casual cooks looking to impress

So, you can cook a decent meal but are looking to give your food that X-factor? To liven up regular dishes, experiment with superfoods which make your meals nutritious and novel. Try combinations like oats chila, quinoa or couscous upmas or a sprinkle of chia seeds in your breakfast pudding. Look for quality imports and efficient distribution for maximum retention of nutrients in superfoods.

Skilled enough to host people? An upgrade from basic ingredients is the most visible sign of your culinary progression. Experiment with exotic herbs like parsley, rosemary and sage as garnishing for intriguing flavours in your soups and salads. For lip-smacking desserts, use exotic fruits like kiwi, dragon fruit, acai berries and rambutan – your guests will be delighted.

For the perfectionist gourmet chefs

You’re quite the culinary expert in your circles, but want to leap to the next level? At the core of a successful gourmet creation lie the best ingredients. Seek a delicatessen which gives you only the freshest and most diverse range of ingredients. You’ll notice the difference in flavours as you move from garlic powder to actual garlic, and from chilli powder to real paprika in your preparations.
