Possibly Oidaematophorus sp? This daytime moth only has a body about 1-1.5 cm long and wingspan of 2-1.5 cm. It is a beautiful deep purple color. The distinguishing characteristic is the double tail. The last picture is only to give some detail on the antenna.
This moth was found on the blossoms of the plant that is used to poison fish. It is abundant in the villages in the Amazon rainforest of SE Ecuador and the blossoms draw a variety of insects. I have submitted the plant but it hasn't been ID'd yet (Search: Fishing Poison Plant from Tukup).
I was actually going to get some pictures of the bees when I noticed the color of this moth and got sidetracked. It is really pretty and, to me at least, unusual with the double tail.
