Female Plain Tiger

I had written long back on Plain tiger (Danaus chrysippus) butterfly. At that time I was using Canon EF 400mm f/5.6 L USM with 36mm of extension tube to photograph this Plain Tiger butterfly. Soon after the Scarlet Skimmer dragonfly photograph session which I published last week, I spotted a female plain tiger butterfly nearby. I used the same setup as I used in the dragonfly photography. My rig consisted of 1D Mark IV camera with Canon EF 300mm f/2.8L + 1.4x tele-converter stabilized on a monopod. Beautiful evening sun gave me plenty of golden light to experiment around this butterfly. It was not at all shy in posing for me as was evident in the photos which is one of the great advantages of using a long telephoto lens for closeup shoots.

As I photographed I noticed that the butterfly had a wound on the thorax at the base of the right hind-wing. The Plain Tiger is protected from attacks due to the unpalatable alkaloids ingested during the larval stages. The larvae pf this butterfly feed on host plants like milkweeds (like Asclepias, Calotropis) which are have toxic alkaloids. The butterfly therefore flies slowly and leisurely, generally close to the ground and in a straight line. This gives a would-be predator ample time to recognize and avoid attacking it. Inexperienced predators will try attacking it, but will learn soon enough to avoid this butterfly as the alkaloids in its body cause vomiting. The butterfly I was photographing also must have escaped such an attack on it.

It was an old wound, the lymph had accumulated and clotted around the right side of the thorax. Even though injured the butterfly was flying normally and was resting like any other of its kind. Tenacity of this butterfly was amazing. The butterfly also has a tough, leathery skin to survive such occasional attacks. When attacked it fakes death and oozes nauseating liquid which makes it smell and taste terrible. This encourages the predator to release the butterfly quickly. The Plain Tiger thus has the ability to recover “miraculously” from predator attacks that would kill most other butterflies.

Even though a macro lens and a flash setup is ideal to get extremely closeup photos of these butterflies, my tele-macro setup works nice. Drawback of this setup is that it needs a good light and is heavy and cumbersome. So it is not very portable. With that setup I can take quite a good amount of closeup shots with a very creamy bokeh effect. I can also using the same setup photograph birds and other distant object which is a real bonus as the same rig works as dual purpose setup.

Chocolate Albatross

Chocolate Albatross

Chocolate Albatross

Monsoon had just begun. It was late evening. Through the incessant drizzle I noticed a small yellow brown butterfly sheltering on the bi-lobed leaves of Malabar Bauhinia(Bauhinia malabarica). On closer inspection it turned out to be a male Chocolate Albatross butterfly (Appias lyncida).

I wanted to take a closeup photo but it was impossible with my Canon EF 100mm f/2.8L Macro IS USM as butterfly was around 12 feet from the ground and all I could get using that lens would have been a tiny image. So I took my Canon EF 300mm f/2.8 L IS USM fitted it with Canon EF 2X II Extender on my Canon EOS 7D thus increasing the focal length to 960mm (in 35mm terms). Now with this magnification I could reach up to the butterfly without disturbing it.

With rain clouds all over the evening sky, Light was fading fast. I used my new Manfrotto 0055CXPRO3 Carbon Fiber tripod to setup the rig. Covered it with Storm jacket to prevent rain damaging the camera and lens. Used my Canon Speedlite 580EX II flash as fill light to get this beautiful shot. Even at full power 580EX was good enough to get f/9.5 at that distance. The depth of field at that distance was razor thin. you can see the eyes are sharp but wingtips are not.

Chocolate Albatross , Appias lyncida is a butterfly of the Family Pieridae. It is found in India, Sri Lanka, Myanmar, Malaysia, Indonesia, Philippines, Thailand, Indochina, Taiwan, Hainan and possibly South China.

In India, the butterfly ranges across South India, peninsular India, Nicobar islands, Sikkim to Assam, and onto Myanmar. In South India, the Chocolate Albatross is to be found along the foot of the Western Ghats. It is found throughout the year in the Nilgiris where it is locally common. In the northern parts of peninsular India it extends into Orissa and North up to Lucknow.

The Chocolate Albatross has a wingspan of 55 to 70mm. The male is white above with chocolate-brown or black margins, and, bright lemon-yellow below with chocolate-colored markings. The female is white and densely clouded with dark-brown.

The butterfly shows seasonal dimorphism and is very variable wet and dry season forms exist.

The Chocolate Albatross is a forest butterfly and prefers rainy highlands, up to a level of 3000 ft. Flying strongly and swiftly close to the ground, the Albatross is frequently found in jungle clearings and along stream banks. The males are often found circling around trees and bushes. The Chocolate Albatross often mudpuddles, sometimes in large numbers. The butterfly occasionally visits flowers and has been recorded to visit Verbena flowers in Kodagu.

The larvae have been recorded on Crataeva religiosa, Capparis roxburghii and Capparis heyneana.

Silhouette

It was late in the evening and light was not sufficient for any meaningful hand held bird photography. I saw the male Loten’s Sunbird(Cinnyris lotenius) on a Peacock Flower (Caesalpinia pulcherrima) plant searching for nectar in the nearby flowers. I had my Canon EF 300mm f/4.0 L IS USM on Canon EOS 7D. The dark dried pod of Peacock Flower was giving a nice silhouette against the setting sun. So I under exposed by 2 stops to get this result with only outline of the bird, complimented by the dried pod. I was on ISO 200 which gave a very sharp outline without any noise.
