Alvares, Rahul; Natural history -- India -- Anecdotes
I learnt from him that butterflies are insects that are more closely
related to plants than to insects. From the number of species of
butterflies in an area, a butterfly collector can also find out the
number of species of plants in that area. This is because each species
of butterfly will use only a certain plant/plants species. For example,
in Goa, there are about 250 species of butterflies, that means that
there are about 900 to 1,000 plant species in Goa. This information
would be much more difficult for a pure botanist to give. Thus
butterflies are an ideal medium for a botanist who wishes to have an
idea of the plant species in the locality.
Eggs are laid by the mother butterflies in distinct places on leaves to
avoid predators from feeding upon them. They hatch within two to three
days. The larvae will moult many times (on an average five) to become a
pupa. During the pupa stage, it does not feed and after a few days it
emerges as a butterfly. It waits for about 10 minutes to dry its wings
in the sun and then flutters away. The whole process to become an adult
may take a period of five weeks to two months. Then the butterfly will
live for about 2 weeks, and within the first few days, will lay only
one batch of eggs.
Moths are the ones that spin silk. No butterfly spins silk. There are
about 10,000 species of moths in the world-much more than butterflies.
Some butterflies and moths are poisonous e.g. the Crimson Rose, even
found in Goa. It is a butterfly with wings and a red body. It also has
red dots on its wings and black dots on its body. The smallest
butterflies are about a few centimetres in size and one of the biggest
butterflies is about the size of two palms put together.
At the end of the meeting Dr Gaonkar showed me some books on
butterflies and some papers written by him on the subject. At around
1.30 p.m. I took leave of him and left for MES College where I had an
appointment with Dr Leela for the same afternoon. There I saw preserved
dolphin tails and specimens of hammer-headed sharks.
My stay in Bangalore also became very special because of the Times of
India programme that Bing managed to arrange for me. The Times of India
in Bangalore has a special section called "Newspaper in Education". One
of the programmes of NIE is to have workshops in schools on varied
topics. On the 20th of January, I went to The Times office on M.G. Road
and after talking with the person in charge for sometime about what I
had been doing during the past year I was asked whether I would take a
few workshops in some schools over the next couple of days. Although I
was not too certain how well I would do this job I agreed because if
there is one thing I learnt during my sabbatical it is that one should
always give a try to anything new because things are not always as hard
as they might appear to be. So I said yes.
