The Life Of Common Rose Swallowtail Butterflies




I have been trying to document the full life cycle of butterflies for sometime. After weeks of searching, I have finally photographed a life cycle of Common Rose----a swallowtail butterfly, thanks to a nature education park near my home.


The Common Rose butterfly is one of my favourite swallowtails even though it is a common species in South and Southeast Asia.  











Its striking red body and the bright red marks on the wings make it stand out not only in its environment but also in the swallowtail family.











The pretty colouration may seem beautiful to us humans but to its predators, it is a warning sign which indicates “poison”.  






In fact, this butterfly is inedible because of the poisons it has obtained from its caterpillar food plant. Its predators seem to be well informed of the danger and often leave this butterfly alone. This strategy works so well that some edible swallowtail butterflies have even learned to mimic its appearance.


When the sun is hot, this butterfly prefers to rest in the shade which gives me the opportunity to get very close.







The egg of Common Rose is very colourful too.


The caterpillar inside this egg seems to be coming out any minute.



The life of the larva, with its poison at hand, is also high profile.  





The pupas, on the other hand, are usually well hidden in small trees not far from its larva plant.

Rare Swallowtail Butterflies


The Swallowtail butterflies are famous for their wing tails but very few can rival the tail length of this White Dragontail. 



Evidently, the White Dragontail does not have the typical characteristics of a swallowtail butterfly (i.e large and colourful). In fact, it is the smallest swallowtail in the world with a wingspan of around 4cm.

The colours of the White Dragontail may be dull, but its flight pattern is exceptional----agile and erratic like a dragonfly. It is rare in Hong Kong and can only be found in a small number of locations.  




Another distinctive feature of this butterfly is that the middle part of its forewings is transparent. This is unique in the swallowtail family. 




In contrast, the Common Birdwing is not only among the largest (wingspan upto 16cm) but also the brightest coloured butterflies of the world. 




Unlike the White Dragontail, the Common Birdwing does not have wing tails at all but has angular wings similar to the shape of bird wings. 




Unfortunately, their size and beautiful colours make the Birdwings very popular with butterfly collectors. In Hong Kong, they are the only butterflies listed as a conservation concern. The butterflies and the food plant of their larvae (Indian Birthwort) are protected by law.

Regarding the rarity of butterflies,  I think not many can beat this Common Mormon. 



Looking carefully, you will find that this butterfly seems to be born with just one wing tail while the other one somehow didn’t develop.  



I have seen tailless polymorphisms before but this butterfly is extraordinary.
