Birdwing Butterflies prints now available on Deviantart!

Hey ya'll

The prints in my birdwing butterfly set have been really popular on deviantart as postcards or prints. Birdwing butterflies are probably one of my all time favorite of butterflies. Not only do their large size make them a breathtaking sight in any setting - both captive and wild - but their iridescent wings and uniqueness to the Southeast Asian region also give them an exotic touch that is quite unique to the species. 

The Southern Tailed Birdwing (Ornithoptera meridionalis) is the smallest of all the birdwing butterflies. Like the Queen Alexandra's birdwing butterfly (which is the largest butterfly in the world) the species was discovered by Walter Rothschild in Milne Bay Province, Papua New Guinea. The species is fairly widespread and may be found in several localities in southeast Papua New Guinea and the southern coast of Irian Jaya. Along with the Paradise birdwing (Ornithoptera paradisea) it is the only butterfly of the birdwing family whose wings are tailed.  Like several other species of birdwing butterflies, it is classified as "endangered" in the IUCN red list due to habitat loss in various parts of Papua new Guinea.  

Conservation initiatives that engage local communities have proven to be fairly successful and there are to date several villages in Papua New Guinea which farm the butterfly for conservation and commercial purposes. The specimens are incredibly valuable and may fetch prices as high as US$1000 per pair. Despite its desirability, collecting of the butterfly has little to negligible effect on its population size provided the original habitats are left undisturbed. The butterflies are remarkable in that they have an extremely small amount of wing area in relative to its large and bulky body. Male butterflies have hind wings that are severely reduced, tapering at the end into a pair of filamentous tails which are easily broken. The males of the species are thus rather clumsy and weak fliers and spend most of their day resting on the canopy layer of primary rainforests. The larva of the butterfly feed on the plants of the genus pararistolochia and incorporate its toxins into its defense system during its development and adult life.  

Ornithoptera priamus, or the common green birdwing, is a very widespread species of birdwing butterfly that is found in New Guinea, Moluccas, the Bismarck Archipelago, the Solomon Islands, and Northeast Australia.  Because of its sizeable range, the butterfly is extremely variable and is believed to have evolved multiple subspecies each exhibiting different markings, patterns, coloration, and forms. According to some experts, there are as many as 99 subspecies of Ornithoptera priamus butterflies although others would contend that some of these subspecies are to be treated as independent species altogether.  Most of the subspecies of Ornithoptera priamus feature brown and cream-patterned females and iridescent green males, although several subspecies such as Ornithoptera priamus urvilleanus, and Ornithoptera priamus miokensis have blue wings. Despite being an overall widespread and established species, some subspecies of the butterfly which are endemic to certain parts of the world are threatened by habitat destruction: primarily the clearing of primary forests (which the butterfly needs for its survival) for the palm oil trade. Many other subspecies, such as Ornithoptera aesacus may be seriously endangered in the wild but otherwise fairly commonly bred in captivity. 

Fun fact: the butterfly is named after Priam, the King of Troy during the Trojan War.

Rajah Brooke's Birdwing Puddling Site


Hey ya'll
First of all, allow me to apologize for the lack of updates. It amuses me somewhat to see that, despite my absence, the blog has continued to receive a fair trickle of visitors! Anyway I just got back from my field work at Ulu Geroh about slightly under a week ago. I am living there with the Semai community, an indigenous group of people of Peninsular Malaysia, as part of the field work process for my PhD dissertation.  Among other amazing natural wonders, such as several species of Rafflesia which flower there, there rainforests surrounding the Ulu Geroh settlement is renowned for having a high diversity of insect species, most notably, butterflies. It is also one of the few remaining sites in Malaysia where the Rajah Brooke's Birdwing butterfly gather in large numbers on the banks of river to imbibe upon the nutrient rich salts that are present in the mud. I shared the video of one such puddling site sometime earlier this week and so it only natural that it would soon be followed by the photographs. Check it out. 

Some of these butterflies grew so "drunk" on salts that they abandoned much of their usual, jittery dispositions and could be coaxed to climb upon my outstretched palm.

Butterfly roosting on the palm of my hand.


Butterflies precariously perched on a layer of algae that has grown over some of the more stagnant puddling sites. Some of these algae platforms "give way" when there are too many butterflies on top of them and the "Drunker" are not always able to react fast enough and  fall into the water.

A first, butterflies puddling on grass!!! Actually this shot was taken very close to a natural hot springs so it is possible that the soil was equally rich in salts and minerals.

Queen Alexandra's Birdwing Butterfly



The Queen Alexandra's Birdwing Butterfly (Ornithoptera alexandrae) is the largest butterfly in the world. It is also one of the few species of butterflies that are truly protected by law. The butterfly, which was named in 1907 in honor of Queen Alexandra of Denmark by Walter Rothschild, measures a whopping 13 inches from one wing to the other and can only be found in a very restricted eco-zone in the coastal rainforests of Oro Province, Papua New Guinea. The butterfly is listed on the Appendix 1 of CITES, which makes all trade of the insect illegal. Specimens of the Queen Alexandra's Birdwing can fetch up to 10,000 US dollars on the black market. Despite this, the main threat to the butterfly's population is arguably not collectors, but the felling of old growth rainforest for plantation land for the palm oil trade which is slowly cutting into the meager 100 square kilometers of rainforest in which the butterfly is exclusively found. The population of Queen Alexandra's Birdwing Butterflies also faced a significant blow during the eruption of Mount Lamington in the 1950s, which destroyed a significant portion of the species' former habitat. 

Like all birdwing butterflies, the Queen Alexandra's Birdwing displays extreme sexual dimorphism. The female, which can reach a wingspan of 13 inches, body length of 3 inches and a body mass of 12 grams (all enormous measurements for a butterfly) is predominantly brown in color with cream or white markings arranged in rows on its wings while the much smaller male displays wings that are an iridescent blue-green in color and have a wingspan of approximately 9 inches or smaller. Male butterflies sometimes develop gold spots on their hind wings and this "atavus" form is often considered to be one of the most spectacular of all birdwing butterflies. 

Female butterflies lay approximately 27 eggs throughout their lifetime on plants of the genus pararistolochia. The larvae imbibe aristolochic acids from the plant's leaves which in turn functions as a potent vertebrate poison that defends them from many predators. The life cycle from egg to pupa takes about 6 weeks to complete. Pupation generally lasts for a month, and the butterflies emerge from their chrysalis only in the early mornings when the sun is not yet at its peak and the air is humid because the enormous wings may dry out before they have fully expanded if the humidity drops. and adult butterflies can live for an average of three to four months. Because of their toxicity and large size they have very few predators aside from large Orb weaving spiders (Nephila spp.) and some birds which have developed methods for eating poisonous butterflies. Adult butterflies are strong fliers and rarely stray from the canopy making them rather difficult to observe. In fact, the first butterfly to be discovered was actually taken with the aid of a small shotgun by Albert Stewart Meek (a collector under the employment of Rothschild) but subsequent specimens were obtained from captive bred stock after Meek discovered the early stages for the species.

Butterfly display case


Hey ya'll 

Just a quick updates before Monday. Display cases an be so difficult and near impossible to locate in Malaysia and so,  I finally decided to invest some time and money into constructing my very own butterfly and moth display case! It wasn't easy, and it cost me a lot of painful fingers, and quite a bit of money... but I daresay the result is well worth it! Anyway I have more buggy delights coming up in the next few weeks or so, so please stay tuned. Somewhat inspired by the success of this display, I'm thinking of constructing another one detailing the life history of various Malaysian cicadas! Stay tuned. 



Cheers,
Cyren.

CITES Teasers Unveiled!!!

Hey ya'll

I know it's been more than one week (or was it two?) since I last dropped the teaser on the CITES permits I got, but here they are!!! My very first set of Ornithoptera, all flexed and ready to spread!!!

Ornithoptera priamus poseidon, male
Ornithoptera rothschildi, male
Aren't they magnificent?! I just can't tell you how nervous I was picking them out of their chambers! One wrong move and it could make all the difference between an A1 specimen and a tear that's going to kill me for the rest of my life (birdwings don't fall out of the sky!!!). One thing to note though, relaxing chambers don't actually work for Ornithoptera. Not when they've (apparently) been dead for over two years!!! Which reminds me, thanks so much to Gregory Nielson and Luan Felipe who offered the advice on injected the butterflies with hot water in the thorax! Worked like a charm it did!!! Anyway, in addition to the two males you see, I've also got two magnificent females on the spreading board. Their size, if anything, is really quite impressive! And speaking of sizes, O. rothschildi turned out to be a lot smaller "in the flesh" than I thought it would be! It's barely larger than one of my medium-large P. memnon specimens. At any rate, do stay tuned for updates!!! I can't wait to remove these babies off the board as I'm sure that they will be exquisitely stunning!!! Also of note are the Parides that also went on the board today!!! Unfortunately a closer inspection revealed two of them to have slightly torn wings!!! Quite a disappointment indeed!!! 

Ps. I just named my Wisdom Tooth. Her name is Wisdy. Wisdy is a real temperamental bitch. Always hurts when I eat nice things. WHY CAN'T I EAT NICE THINGS? I think Wisdy should be more like Dom (my other Wisdom tooth) He never seems to cause a fuss. Just sayin'. 


Cheers

Teasers


Hey ya'll 

so the butterflies arrived in the post today and in addition to the six beautiful S. American swallowtails that were in the package, I also got two magnificent beauties that came with their very own CITES permits.


Stay tuned for updates.
