Glassy Tiger

A Glassy Tiger (Parantica aglea) photographed in Anuradhapura

The Glassy Tiger belongs to the Danaid group of butterflies, which includes crows and Tigers. It's habitat includes India, Sri Lanka, Nepal and Burma. Two subspecies have been identified but neither of them are consistent in markings or habitat. More info and images inside.

The male Glassy Tiger has scent patches on the hind wing. The pouch on vein 1 is larger than the pouch on vein 2 and both pouches are  more visible on the underside than on the upper side. It is a very common butterfly in Sri Lanka and can be found up to an elevation of 5000 feet. It is found all over the island except for the north where it is uncommon.

The flight of the Glassy Tiger is very weak and it flaps its wings a lot during flight. it spends most of its time within 5-10 feet of the ground and rarely visits the canopy.  It is often found in the company of other males in the Danaid family, when they gather on plants. The Glassy Tiger frequently visits flowers in the undergrowth for nectar and the male occasionally settles on wet soil.

The Glassy Tiger mimics an unpalatable poisonous species of butterfly and is avoided by birds and lizards. It also has tough leathery skin which helps it survive the occasional attack. When it is attached, it fakes death and oozes a nauseating liquid which makes it smell and taste awful. It also has the ability to recover from an attack very quickly.

These images were captured with a Canon 7D and the 100-400mm lens, in Anuradhapura.

Common Jezebel

The Common Jezebel is a medium sized pierid butterfly found in many areas of South and Southeast Asia, especially in the non-arid regions of India, Sri Lanka, Myanmar and Thailand. More images and info inside.

The wingspan of both males and females range from 6.5cm to 8.5cm. The upper and under sides of the females wing  are similar to the male but the black edging to the veins and the postdiscal transverse bands on both fore and hind wings are much broader than that of the male.

This butterfly is common through most of its range except for the desert tracts, and up to an altitude of 7000 feet. It can be found wherever there are trees, even in towns and cities. The females can be seen flying amongst the trees in search of its food plants, while the males are more frequently observed visiting flowers for nectar or mud-puddling. It rests with its wings closed exhibiting the brilliantly coloured underside.

 

It has bright coloration to indicate the fact that it is unpalatable due to toxins accumulated by the larvae from the host-plants. Like other unpalatable butterflies the Common Jezebel is mimicked by Prioneris sita, the Painted Sawtooth. The Common Jezebel can be distinguished by the shape of the orange red spots on the hind wing. In the Painted Sawtooth these spots are very squarish whereas in the Common Jezebel they are more arrow head shaped. The Painted Sawtooth also flies faster and will also mud puddle.

All the shots on this post have been taken with the Canon 7D and the EF 100-400mm lens. I used an ISO of 400 hoping to utilise a faster shutter speed and minimise the noise. I managed to get within 2 meters of the butterfy tocapture these images. The butterflies were photographed in Anuradhapura, Trincomalee and Colombo. The largest specimens were seen in Trincomalee.

Glassy Tiger

The Glassy Tiger is a common butterfly found at an altitude of up to 5000 feet, over most of the island. More info on the butterfly and the image inside.

With a wingspan of 65-80mm it is the slowest of the Danaids. It spends much of its time between 5 and 10 feet and rarely flies up into the canopy. It is the most shade loving of all the Danaids and is frequently seen nectaring on flowers in the undergrowth. It has a chemical defense that protects it against predators. When handled, it plays dead and emits a foul smelling substance. The sexes are similar.

The male has scent patches on the hind wing. The pouch shaped patch on vein 1 is larger than the pouch on vein 2. Both are more swollen and visible on the underside than on the upper side. The markings on the Glassy Tiger are uniformly grey. It is also the smallest butterfly in the group.

The Glassy Tiger is similar to the Blue Tiger, Dark Blue Tiger, Female Dark Wanderer and the Common Mime.

The fact that it is slow in flight probably helped me when it came to capturing the image above. I followed it as it settled on a number of different flowers until I finally got the shot I was after. I used the 100-400mm lens for this and therefore I didn't have to get too close to it. I came across this butterfly in the middle of the afternoon which is probably the worst time to photograph Butterflies. The best time to photograph them is early morning before they "warm up" in the sun and become more active. Make sure that your shadow does not fall on the subject when you approach it as that tends to disturb them.
