The Month of January is named after the ancient Roman God 'Janus' who is the God of doorways, of beginnings, and of the rising and setting of the sun, usually represented as having one head with two bearded faces back to back, looking in opposite directions, one looking at the past and the other looking forward to the future.
This colourful caterpillar which I noticed on a Milkweed Plant, Calotropis gigantea (also known as Crown Flower or "Erukkampoo" in Tamil) resembled a Railway locomotive which could travel in both directions. In fact I had a bit of difficulty in identifying the head of this Caterpillar, as it exhibits perfect symmetry and when viewed independently both ends of the train look like a Head :)
Although I had shot this image in the middle of December 2011, I could find the details only today thanks to Lawrence Duhon. This insect is the Caterpillar of the Queen Butterfly Danaus gilippus(Milkweed Butterflies)
Wishing you all a Happy New Year 2012.
