Curinus coeruleus (Metallic Blue Lady Beetle) (?).
It is metallic Blue all over and 3/4 the size of a normal Lady beetle.
There suppose to be two orangish "spots" left and right of the mouth, but there is none, and it suppose to have orangish "legs" but the legs a metallic blue too.
Here it is sleeping on a Dendrobium Softcane leaf. (See also photo 2 & 3)
