Acosmeryx Hawk Moth

It was my first time to see this moth and I thought I was seeing a dark Oleander Hawk Moth. I saw it after a heavy rain in the morning, struggling to move and fly but was not able to go far, and just rested on the leaves of an ornamental bamboo plant inside our garage. When I checked on it again that afternoon, it was already dead and the ants had taken over its body :(.

This is an Acosmeryx anceus subdentata Rothschild & Jordan, 1903.
