Dr Seow,

Thank you for your prompt reply.

I understand that the A moorei may have been sighted in the Central Catchment Reservoir area.
My apologies that I am totally new and know very little about Arhopalas. They are rather challenging species. How then do we differentiate both these Arhopalas if I should encounter the species again?

By the way, I got the common name of the A. muta, ie Mutal Oakblue from Khew's Butterflies of Singapore book.
