Black and Yellow Flat Millepede
Even though this is a very common millipede in our garden I was not able to identify scientifically. This resembles morphologically the Apheloria genus found in America, but I doubt it belongs to that.
They do not bite humans. Generally found in leaf litter , millipedes tend to avoid light and may discharge a foul odor by secreting 2-Nitroethenylbenzenes to discourage predators. Pachydesmus crassicutis is known to produce hydrogen Cyanide gas to repel predators.
Millipedes, are arthropods that have two pairs of legs per segment (except for the first segment behind the head which does not have any appendages at all, and the next few which only have one pair of legs). Each segment that has two pairs of legs is a result of two single segments fused together as one. Most millipedes have very elongated cylindrical bodies, although some are flattened dorso-ventrally, while pill millipedes are shorter and can roll into a ball, like a pillbug.
Millipedes are detritivores and slow moving. Most millipedes eat decaying leaves and other dead plant matter, moisturising the food with secretions and then scraping it in with the jaws. However they can also be a minor garden pest, especially in greenhouses where they can cause severe damage to emergent seedlings. Signs of millipede damage include the stripping of the outer layers of a young plant stem and irregular damage to leaves and plant apices.
This class contains around 10,000 species. There are 13 orders and 115 families.
The giant African millipede (Archispirostreptus gigas) is the largest species of millipede.

Canon EF 100 f/2.8L Hybrid IS Macro
Hot on the heels of Canon’s announcement of its Hybrid IS technology comes the first lens to sport this feature and, to no great surprise, it’s a 100mm F2.8 macro. The Hybrid IS system is claimed to provide up to 2 stops stabilization at 1.0x magnification, and up to 4 stops at longer shooting distances. This, Canon’s third-generation EF 100mm F2.8 macro lens, is also the first to gain the flagship ‘L’ designation and comes with such goodies as ultra-low dispersion glass elements, a nine blade circular aperture and weathersealing. The Canon EF 100mm F2.8L IS USM macro will supplement, rather than supplant the existing 100mm F2.8 USM macro. I plan to buy as soon as it is available in India.
Check out this article from DPreview or from canon site for more details.

Common Wolf Snake
Last time when I saw this Common Wolf Snake (Lycodon aulicus) it was juvenile. I saw this snake on Nag Panchami Day a day of revering snakes 
. I am not really sure it is the same snake or any of of its brethren. But surely it had grown up and developed a nice bands which made this non-poisonous look like poisonous snake Banded Krait. This was a nice example of Batesian Mimicry.
Close up of the head
These bands were not visible in the juvenile which I photographed earlier. Snake was as easy to handle as before without showing any aggressiveness.
Common Wolf Snake
I photographed and released the snake back in my backyard, so that I will have another glimpse few days or weeks later.
