The Red Pierrot (Talicada nyseus)
The Red Pierrot (Talicada nyseus) is a small but striking butterfly found in South Asia and South-East Asia belonging to the Lycaenids or Blues family. Red Pierrots, flying weakly around and perching on the Kalanchoe plant, are usually noticed by excited children in gardens due to their beautiful striking patterns and colours.
The butterfly with a wing span of 3 to 3.5 cm. The upper side of its wings are black except for a large portion of the lower edge of the hind wing which is orange.
On the underside, the forewing is white with black spots more toward the margin. The hind wing is very striking, it is white with black spots toward the base and the margin has a wide band of orange with white spots. There is a lot of variation found in the blacks spots on the hind wings.
Males and females. Upperside: black or brownish black, in fresh specimens in certain lights with a dull purplish flush. Fore wing: uniform, with a very slender thread-like edging of white to the costa. Hindwing: a large conspicuous orange-red patch on the posterior terminal half of the wing between the dorsum and vein 7; this patch does not extend quite to the termen but leaves a narrow edging of the black ground-colour which is produced inwards in short conical projections in interspaces 2 to 5. Cilia of both fore and hind wings chequered with black and white alternately. Underside: silvery white. Forewing: a quadrate spot on the discocellulars, a broad transverse discal band and the terminal third of the wing jet-black; the discal band is irregular, dislocated on vein 3, the posterior portion shifted inwards and joined on to the black area on the posterior terminal third of the wing by projections of black on the dorsum, along veins 3 and between veins 4 and 5; the black area on terminal third of the wing encloses a transverse postdiscal series of small round and a subterminal transversely near series of spots of the white ground-colour. Hind wing: two spots near base, a subbasal transverse series of three spots, a medial similar series of four somewhat elongate spots and a transverse short postdiscal bar between veins 4 and 6, jet-black ; terminal third of the wing above vein 7 jet-black, below that vein deep orange-red, the whole area (both the black and the red) medially traversed by a transverse curved series of round spots of the white ground-colour and margined outwardly by a series of transverse, very short and very slender lines of the same in the interspaces; anticiliary line black. Cilia of both fore and hind wings chequered as on the upperside; a short filamentous tail at apex of vein 2 black, tipped white. Antennae, head, thorax and abdomen black, shafts of the antennae ringed with white ; beneath: palpi, thorax and abdomen while.
Sri Lanka, South India, Meghalaya, Assam, North Myanmar.
Locally abundant. Widely distributed in Peninsular India, and has been recorded from many localities in Maharashtra, Karnataka, Punjab, and Orissa. Also found in the hilly regions of NE India and northern Myanmar. Studies suggest that they may be on the way to colonizing the foothills of the Himalayas due to changes in the habitat.
Found in semi-arid plains, degraded patches of evergreen patches, and semi-evergreen forest, gardens, hill stations and forests, in fact wherever its foodplant, Kalanchoe, is abundant. It is found from the plains to 8000 feet.
The Red Pierrot is a weak flier, and flutters about close to the ground. It flies in short bursts and settles often but not for very long. It basks with its wings half open, but prefers shade to sun and jungle or undergrowth to open areas. It keeps on the wing almost till dark when it settles on the undersides of leafs and twigs often in company. It is sluggish early in the morning and late in the evening. It visits flowers of herbs especially of the amaranthaceae and acanthaceae family for nectar. It visits both ornamental and wild flowers and varieties of Alternanthera are among its favourite.
It always sits with its wings closed to display the bright markings of its undersides. It fearlessness, weak flight and distinctive markings all indicate that it is a protected butterfly, which is peculiar considering that its hostplants are not known to contain any sequestrable toxins.
There is a mention in literature of the species being found at lights at night, however such phenomena are usually restricted to species that are crepuscular and this occurrence may be incidental.
It is not a common butterfly, but near its food plant, Kalanchoe, it is found in abundance and is gregarious in all its stages.
The female lays eggs on the underside of a leaf. Young and old leaves are selected without discrimination as the leaves of Kalanchoe are thick and succulent during all stages.
The caterpillar is pale yellow to a dirty white, and flattened with large, jet black spiracles. The entire body is covered with tiny white setae or bristle-like hair.
This caterpillar is a leaf miner by habit and this serves as its defense. As soon as it hatches it bores into the leaf and will spend the rest of its life between the epidermal layers of the leaf. Occasionally it will change leaves.
The caterpillar tunnels through the entire leaf in a neat winding manner so as to make sure to consume the entire leaf. It leaves a black trail within that is filled with droppings. The caterpillar can only be seen when it is changing leaves or when it comes to the surface to pupate.
Onisciform, but much rounded, and with the segments at the divisions very clearly defined; head small, almost concealed; last segment flattened. It is in colour fleshy-white, with a row of nine small black dots along the back on each side and a ring of four similar dots on the segment nearest the head; it is profusely covered with small white hairs. It feeds in the interior of the fleshy leaves of Bryophyllum calycinum, only emerging in order to turn into a pupa.
At the time of pupation the caterpillar comes out of the leaf and weaves a silk pad and a tight body band and then moults to form the pupa. The pupa can be either on the under or upper surface of the leaf. It is yellow and covered with long light hairs. The pupa is also marked with numerous black spots all over the body.
... much resembles the larva, being short and stout and blunt and covered with short-white hair. It is of the same fleshy colour as the larva and has two lines of small black dots along the surface of the abdomen continued along the thorax. It also has a third row of four similar dots on the middle of the abdomen between them; the two dots on the thorax nearest the head are also connected by two other dots.
The larval host plants are Kalanchoe laciniata and K. pinnata of the family Crassulaceae (Stonecrop family); the latter host being a common garden plant. Adult butterflies have sometimes been seen to visit lichens. Studies suggest that they collect phenolic substances by scraping lichens
Pigmentation in some Butterfly Wings created by Nanostructures
ScienceDaily (Jan. 22, 2008) - Nowhere in nature is there so much beautiful colour as on the wings of butterflies. Scientists, however, are still baffled about exactly how these colours are created. Marco Giraldo has been examining the structure of the surface of the wings of the cabbage white and other butterflies. Among the things he has discovered is why European cabbage whites are rebuffed more often than Japanese ones. Giraldo will be awarded a PhD by the University of Groningen on 25 January 2008.
The colours on butterfly wings are used as an advertisement. The patterns on the wings enable butterflies to recognize their own species at a distance and differentiate between males and females - rather handy when you're hunting for a partner. Just like a pointillist painting, the surface of the wing is constructed of a huge collection of coloured dots, called scales, each about 50 x 250 micrometers in size.
However, scientists don't yet know very much about how the colour on the wings is formed. What they do know is that the colours are created in two different ways: via pigments and via nanostructures on the scales, which ensure that light is distributed in ways that are sometimes spectacular. These so-called structure colours can clearly be seen on the morpho butterflies of the South American rainforests.
Butterflies Use Polarized Light To Attract Mates
ScienceDaily (May 1, 2003) - Up to 20 layers of transparent scales on butterfly wings scatter white light to produce brilliant blue structural color. Alison Sweeney, Duke University, and collaborators at the Smithsonian Tropical Research Institute report in Nature that polarized light from iridescent female Heliconius butterflies functions as a mating signal. This may be the first example of mate recognition based on polarized light. Physical properties of wing scales may play an important role in speciation of Heliconius butterflies.
People in small planes flying low over tropical forest often comment about the tiny flashes of blue from iridescent butterfly wings that stand out against dark green jungle foliage. But the ecological significance of light scattering and shaping by butterflies has, for the most part, been overlooked.
Sweeney brings a new emphasis on the physical properties of butterfly wings to a group studying the genetics and ecology of speciation in Heliconius butterflies. She presented moving female butterfly wings to conspecific males with and without filters that eliminate polarized light. Males of an iridescent species approached females producing polarized signals significantly more often when signals were not depolarized. Males of another, non-iridescent species approached females, which do not produce polarized signals, at the same rate regardless of the presence or absence of the depolarizing filters.
Differences in light bending by genetically inherited patterns of butterfly scales may be important in sexual selection and speciation of Heliconius butterflies and may vary according to the specific light environment they occupy in tropical forests.

Secrets Behind Butterfly Wing Patterns Uncovered
ScienceDaily (Oct. 26, 2007) - The genes that make a fruit fly's eyes red also produce red wing patterns in the Heliconius butterfly found in South and Central America, finds a new study by a UC Irvine entomologist.
Bob Reed, assistant professor of ecology and evolutionary biology, discovered that genes involved in making insect eye pigments evolved over time to also make wing pigments in butterflies. This finding sheds light on the genetic causes of wing patterns and why, in the Heliconius, those patterns can vary widely from region to region.
'We found that evolution is achieved primarily through recycling old genes into new functions, as opposed to evolving entirely new genes from scratch,' Reed said.
Within one species of the butterfly genus Heliconius, more than 20 distinct wing patterns can exist in different geographic regions. Over time, the Heliconius evolves to look like local unrelated butterfly species that are poisonous to birds, a phenomenon called mimicry.
'It is a very basic textbook example of natural selection,' Reed said. 'If you look like you're poisonous, you're not going to get eaten and you can produce offspring.'
Reed's study also explains under which conditions certain genes will cause a stripe on a Heliconius wing to become yellow or red.
W. Owen McMillan of the University of Puerto Rico and Lisa M. Nagy of the University of Arizona also worked on this study, which was funded by the National Science Foundation and a University of Arizona IGERT genomics fellowship.
UC Irvine has two additional butterfly experts - Adriana Briscoe, who studies butterfly eyes and color vision, and Tony Long, who studies eyespot patterns on butterfly wings. All three scientists are members of the Department of Ecology and Evolutionary Biology in the School of Biological Sciences.
Results of the study appeared online in the Proceedings of the Royal Society B.
