Yellow Chested Carpenter Bee
The newly acquired Canon EF 300mm f/4.0 L IS USM lens has proved great while taking fast flying insects like these carpenter bees. They don’t stop at any flower, zooming from one to another Rattleweed plants (Crotalaria retusa). Carpenter bees are known to rob nectar by slitting the sides of flowers with deep corollas. Their name comes from the fact that nearly all species build their nests in burrows in dead wood, bamboo, or structural timbers (except those in the subgenus Proxylocopa, which nest in the ground).
Carpenter bees are traditionally considered solitary bees, though some species have simple social nests in which mothers and daughters may cohabit. However, even solitary species tend to be gregarious, and often several will nest near each other. It has been occasionally reported that when females cohabit, there may be a division of labor between them, where one female may spend most of her time as a guard within the nest, motionless and near the entrance, while another female spends most of her time foraging for provisions.
Carpenter Bee nest in a tree trunk
Carpenter bees make nests by tunneling into wood, vibrating their bodies as they rasp their mandibles against the wood, each nest having a single entrance which may have many adjacent tunnels. The entrance often is a perfectly circular hole on the underside of a beam or tree limb. Carpenter bees do not eat wood. They discard the bits of wood, or re-use particles to build partitions between cells. The tunnel functions as a nursery for brood and the pollen/nectar upon which the brood subsists. The provision masses of some species are among the most complex in shape of any group of bees; whereas most bees fill their brood cells with a soupy mass, and others form simple spheroidal pollen masses, Xylocopa form elongate and carefully sculpted masses that have several projections which keep the bulk of the mass from coming into contact with the cell walls, sometimes resembling an irregular caltrop. The eggs are very large relative to the size of the female, and are some of the largest eggs among all insects.

Metallic Black Carpenter Bee
I spotted two variety of Carpenter bees, one which was having yellow chest which is quite often confused with bumble bees. Most carpenter bees have a shiny abdomen, while in bumblebees the abdomen is completely clothed with dense hairOther was a classic blue eyed black metallic carpenter bee. These bees belong to Xylocopa Genus. I was not able to determine the exact species.

Fire Breathing Tiger
After using Shiva‘s Canon EF 300mm f/4.0 L IS USM, I was very impressed with the result. I wanted to buy this lens. Right at that time I saw the sale of this lens at JJ Mehta Forum and went to get it. It reached me on 26th September 2009. I thank Siaon for selling me such a beautiful lens.
Same evening there was immersion of Sharada Idol taken in procession was going on as part of Dasara Festival. and It was best time to check out my newly possessed lens. Here is the shot taken in existing light of the tiger dance (hulivesha) artist breathing fire.
Tiger Dance is a unique form of folk dance in Dakshina Kannada that fascinates the young and the old alike. Since tiger is considered as the favored carrier of Goddess Sharada (the deity in whose honor Dasara is celebrated), this dance is performed during the Dasara celebration. It is also performed during other festivals like Krishna Janmasthami & Ganesh Chathurthi. There are over 150 troupes who perform this famed folk dance.

Fatal Attraction
I was trying to test Canon EF 300mm f/4.0 L IS USM which was courteously provided by Shivashankar with my Canon EF 1.4x II Extender when I spotted these mating Common Grass Yellows(Eurema hecabe) on a Peacock Flower (Caesalpinia pulcherrima) plant. On closer inspection there was this dark brown spider stuck on the head of the male. I wanted to capture the whole sequence so I quickly changed to my Canon EF 100mm f/2.8 USM Macro with Canon MT-24EX macro twin light flash and captured the whole sequence. I have posted 4 most interesting shots from this sequence.

Fatal Attraction
This Adanson’s House Jumper (Hasarius adansoni) had caught hold of the male by the head while in the act of mating. It had killed it and is now proceeding towards the female which was still stuck to the mate.

Fatal Attraction
It was a precarious perch for the spider as it had to manage the dead body of one and struggling butterfly on the other. The female was desperately trying to escape from the clutches of the spider but was unable to do. Spider manage to twist and turn the body of the dead male and lurched forward to reach for the female.

Fatal Attraction
After nearly 15 minutes of struggle the female managed to tire out the spider and gain the upright position. With bit more struggle she was able to release herself from the mate and fly away free and alive. It was such an awesome sight that I was amazed how she managed to do that.
