Phalera reya

Last Observed: 2015, Koh Chang
Observed By: Hans-Henrik Hansen
Phalera reya is a brilliant imitator. When perched with its wings folded it looks exactly like a small twig. The level of detail is impressive, there is even a patch of ‘lichen’ featured on each wing.

Peridrome orbicularis
Last Observed: 2010, Koh Chang
Observed By: Dave Hinchliffe
Poor old Peridrome orbicularis. It doesn’t seem to have a common name – just the Latin one. You would think that some moth-spotter somewhere would have considered it beautiful enough to merit its own common name – even if it was something as prosaic as “Black-spotted orange moth”.
Maybe it has a name somewhere and we just haven’t found it yet.
Until then, at least on Koh Chang Nature, it shall be known as the Tequila Sunset Moth.

Garden or Writing Spider (Argiope sp., Araneidae)
Image Copyright David Newman
Observed: October 2015, Lonely Beach, Koh Chang
Observed By: David Newman
This spider is of the genus Argiope which are commonly known as garden spiders. It looks like the yellow garden spider but since they are common to North and Central America one it probably isn’t unless it hitched a lift in a backpack. It’s a close cousin anyway, feel free to let us know if you find the exact species.
As with most spiders the female garden spider is far larger than the male. They lay 400 to 1,400 eggs. They will kill insect prey up to twice their size and, reassuringly, they are harmless to humans.

Indian Cushion Seastar (Culcita schmideliana)

Observed: Koh Chang Reefs, February 2010
Observed By: Jonathan Milnes
The Indian Cushion Sea Star is a large and, you guessed it, cushion-like species of starfish found on Koh Chang. It has a a very different shape to the more typical five-armed examples of the starfish family but if you look closely you can still see the pentagonal shape of the animal.
Starfish are not, as many people think, members of the Mollusc family, they are in fact classified along with sea wasps, sea urchins and brittle stars as Echinoderms. I’d be lying if I said that I knew that when I started writing this.

NB: Clearly the two spiders pictured are different species of spiny orb-weaver. If someone can identify the black and white one we’ll add another page.
Day-Flying Moth Caterpiller (Cyclosia papilionaris)

Last Observed: November 2005, White Sand Beach – Koh Chang
Observed By: Dave Hinchliffe
This astonishing looking caterpillar is in fact the juvenile form of the Day-Flying Moth. It also goes by the more appropriate name of Drury’s Jewel. It is covered in yellow coloured protrusions with just six that are red in colour.
Surprisingly the moth that it eventually transforms into is a simple black and white colour. Where all that colour goes is anybody’s guess.
