Thanks, @ChunXingWong for the likely ID.
The guy in KL (KurtOrion) who did a lot of herping trips have taken quite a few pictures of this Spider at various places in Peninsular Malaysia and he IDed them as Poltys mouhoti - Mouhot's Rolled-leaf Spider. And as you mentioned, Wikipedia indicates that Poltys mouhoti is reported from Vietnam. However, it is most likely due to lack of field data. Maybe you can go and collect them to study it, if it could be a new species or at least a sub-species ;)
Thanks, @Lauren, @Mark and @shekainah :)
Rajah Brooke's birdwing (Trogonoptera brookiana) is a birdwing butterfly from the family papilionidae of butterfly. Both sexes resemble the more restricted relative, the Palawan birdwing, but males of Rajah Brooke's birdwing have more green to the hindwings. The wingspan of Rajah Brooke's birdwing is 15–17 cm (5.9–6.7 in). The wings of males are mainly black. Each forewing has seven tooth-shaped electric-green markings, while there is a relatively large metalic green patch on the hindwings.
For the developers at New York start-up Networked Organisms, smartphones are the butterfly nets of the 21st Century. Their tool, Project Noah, lets people upload photos of plants and wildlife around them, creating a map of the natural world and contributing to scientific research in the process.
Bespectacled scientists of yore would carry around hefty field guides, made up of hundreds of pages of text and photos. But these days, smartphone owners have a lighter option: an app called Project Noah, which aims to help people identify plants and animals as well as collect data from "citizen scientists" about where certain species are located.
Project Noah enables us to be part of a more focused online community where we can learn more about wildlife around us and contribute to scientific research. It pulls participants into deeper, more meaningful engagement by enabling people to go on “missions” to collectively map changes based on sightings.
A modern invention that may also hold the key to saving species in the future. Project Noah is a global study that encourages nature lovers to document the wildlife they encounter, using a purpose built phone app and web community. In addition to the virtual "collection" of species, Project Noah encourages citizen science by linking up with existing surveys including the International Spider Survey and the Global Coral Reef Monitoring Network.
