The postman knocked twice

They picked me up today, from the gloom of the events of this last week.
And I hope they do the same for all of you.

Remember the Red-capped postman, who came knocking this April?
Well, they visited again,
via email.
Courtesy Mr Ramanan, who sent them a few weeks ago...

More talented than Mr Ripley!

Thats what I thought while reading about butterfly mimicry.  The "talented" Mr Ripley. pops off his friend, and takes on his persona.  While butterflies mimic other butterflies so that they dont get popped off.

It all gets a bit confusing, but I discovered that this butterfly mimicry is a serious area of scientific research, and scientists have found the gene responsible for butterfly mimicry!!

So, if what I've understood is right, a nice tasty, colourful butterfly pretends to be a toxic, colourful butterfly, and fools the birds and reptiles to leave it alone.  Now for all of this to work, there should be enough of the original toxic butterflies around, so the pretenders can get away with their disguise.

The scientist who discovered this was somebody called Bates, and so, it seems, this whole behaviour is referred to as Batesian mimicry.

What I cant figure out is, how do we know then that it is actually butterfly A and not butterfly B which it is disguised as?!

I saw loads of these two butterflies flitting around on the meadows a couple of days ago.  I was filled with childish delight and wonder as they flitted from one little purple meadow flower to another,  alighting on a tall grass flower, and swaying with the breeze.

I had my binocs (for once!) and so had my heart's fill of  following them around.  But for a camera, I only had my 'phone.  Oh well, I shouldn't complain.  

So I came back home referred to my books, and said to myself,"Aha, an eggfly (the black, polka-dotted one), and a plain tiger (the yellow one).  Feeling very pleased at my idying abilities, I was about to move on, when my eye caught sight of an article/picture that said, "An eggfly pretending to be a plain tiger".  What?!  I took a look - several times - between the supposed difference between a plain tiger and an eggfly pretending to be a tiger, but I couldn't see the differences, in spots, border patterns, etc etc that i was supposed to look for.

So it turns out, that this pair are a male and female of the same Danaid eggfly.  Or so I think, anyway.  
As I ambled to the banks of the estuary, I saw these lovely candle bushes, all abloom and buzzing with bees, as also some Cassia.

And these purple wonders, which I cannot identify,

As also this blue tiger.  Parakeets screeched overhead, while the clouds seem to have driven away the Kites, which I usually would see circling here.

On the water, were a whole bunch of egrets, black-winged stilts and some other waders that were too far away for me to see.

But what I liked most were those barn swallows.  These birds, I believe are only winter visitors to Madras, spending the rest of the year somewhere in the Himalayas!  Their flight paths and speed are quite astonishing and I spent so much time watching them fly, dive bomb, turn on their tails....puts any fighter plane to shame!

Check out these lovely pictures from another MNS member Sripad.  He saw them at Adyar Poonga.

The Arte Y Pico award

Early November, I received an "award".  Yes, yes strange things do happen in this world!  Here, I was rambling away, and I get an award for creativity and art!!

Raji ruled that she would bestow me with the Arte Y Pico award.  Thank you Raji!  

Like any good award winner, I shall now proceed to thank my friends, "fans" and of course my family!!  

Much of the content on this blog revolves around the photos taken by my husband, as well as some spectacular ones by Mr Ramanan, so my sincere thanks to them.  To my son for being the most critical reader of this blog, and for whom I actually started jotting down these ramblings.  And to Kamini, my most encouraging reader, who always has something nice, positive and relevant to say about my posts.

To MNS for introducing me to some great people, opening my eyes to the wonders of Nature, and bringing a joie de vivre and camaraderie to our outings!

Here are the Arte Y Pico Award rules :

1. You have to pick 5 blogs that you consider deserve this award through creativity, design, interesting material, and also contributes to the blogger community, no matter of language.
   
2. Each award should have the name of the author with a link to their blog.
   
3. Award winners have to post the award with the name and link to the blog of the person who gave them the award.
   
4. Please include a link to the “Arte Y Pico” blog so that everyone will know where the award came from.

So now I have this most enjoyable job of passing on this award, so here goes:

Kamini, whose Tales of South India, are so wonderfully imaginative, heartwarming and gripping.
Maiji, who recounts her Memories of Life in Pondicherry with such clarity, affection and humour
Amila Salgado, from across the Palk Straits for such great photos of the little creatures that we tend to ignore at Gallicissa
Keith Stanley whose creative and beautiful Ikebana I can look at over and over again, at the Sogetsu Atelier
Jyotsna for her World of Words, recounting and sharing the special joys that her child brings to her.

Another great peacock picture

Mr Ramanan sent along another peacock picture, and I have updated the post Peacock - What a bird.

Why Do Fall Leaves Change Colour?

That's the question that intrigued me recently, when Chitrakka sent me an album of fall colours in New England. In a strange moment of serendipity, just yesterday I saw a cartoon in the newspaper about a little boy asking his mum about whether she knew why leaves change colour in the fall. In the cartoon, the mom launches into a romantic explanation involving God, Nature and Beauty. The next frame shows the boy drily saying isnt it because there's less sunlight and the plants are producing less chlorophyll?!

There's so much beauty in fall colours that I just gawp at pictures, and have never found out why. (And if they did teach me in school, I've long since forgotten!) So, deciding to re-educate myself, I googled away.

National Geographic had this nice essay, where I was informed that the lower levels of light means lower levels of chlorophhyll and the caroteinoids (which were always there) begin to show themselves.

It got a bit more complicated as I read further - there is also anthocyanin produced in the cooler months (the flaming red colour-giver), though from what I read, its role is a bit of a mystery. Hmmm... Scientists are doing extensive research as to why some turn golden and some turn red. And both seem successful at keeping the tree alive!!

Well, couldn't it just be that the maple thinks red is cool and the aspen loves yellow?! I mean imagine if a Martian were trying to research why some human females chose pink dresses, others black and still others yellow, green and blue!! They will be kept busy for a long time!!

Update:

Kamini sent me these aboslutely gorgeous photos of fall colours in Westchester, USA this year.

See, some like it yellow, others red!

Lovely photos, Kamini, and thanks for sending them along!
