Black and Yellow Butterfly

Earlier this year, I visited a show of tropical butterflies. It was cold outside and way too hot and humid inside. However, the water drops dripping about everywhere made for some really nice pictures with the colorful butterflies:

Notice how the narrow depth of field draws your eyes to the eyes of the butterfly. I feel as though it will dip into the drop of water for a quick drink before taking off again.

Unfortunately, I did not take any notes and I can not find the name of this wonderful little critter.

For the technical minded: the picture was taken in available light at ISO 400, 1/80s, f/2.8. It would interest me to see how the image would look at f/4 or even f/8 with increased depth of field to include the butterfly wings ... next time. :-)
