(vm.bharathiraja) Life experiences accidental variations and one of this animal's distant ancestors did not get eaten by a bird because it looked a little bit like a leaf. It's offspring looked like it (and therefore slightly like a leaf). The birds then found some of those children except for the ones that looked even more like a leaf. etc. etc. x100000 until today they all look very much like a leaf.

Mark,
Thanks for such a brief answer and your time.I feel your answer says separation from all.i.e.Survival of the fittest.

But I just want to go deep.Homo sapiens ,we are hiding ourself from enemies by wearing camouflage cloth (military).We are having reasoning sense.

But does the insect know that it is camouflaged.

Yes, stay safe when out there, John.

Yes John.. the world is watching. Stay safe.

I'm grateful too for your contributions guys. In fact I never thought there is this kind of insect in the area and there maybe more unrecorded species , its just bit difficult to explore the place because of the never ending armed conflicts in the area.

Thank you for your contributions on this spotting Mark and Albert! As the discussion goes on re. ID and the spotting is highly popular on our official page I'm leaving it in the spotlight for another day.

@Mark, visually, this one does not match Phyllium bioculatum too.
The lobes/appendages on the legs of P.bioculatum are much bigger.
The end of abdomen of P.bioculatum is flat or squarish, whereas this one is pointed.

I don't suppose someone's pet has escaped !? LOL

Thanks Albert. I couldn't see anything wrong... glad to have an expert. :)
Sorry John I should have checked range properly.

@Mark, this is not Phyllium bioculatum which is not recorded from Philippines.

The nearest likely sp is Phyllium ericoriai known from south Luzon and nearby islands including Marinduque.

As this could be the first documentation of Phyllium from Panay Island, it is not possible to verify with certainty that it is Phyllium ericoriai.

Nice Spotting, Joahn Alaban. Would be a nice addition to this Mission :

@Mark Ridgway - Thanks for the ID Mark :) .

Yes Mark it might,since guava is a very common fruit tree in our country both in populated and forested area in fact there mountainous peaks here where almost 90 % of the surface is dominated by wild guavas.

I read somewhere that they are mimicking guava leaf.

How this camouflage is formed through evolution?
