Hungry Butterfly

Just outside of our house we have several tree stumps where we place food for the birds to come eat throughout the day...typically we will put out different fruits for the birds to come and enjoy...we had this butterfly perched on the stump for a few hours just hanging out and grinding (eating), until mark came along and scared him off...i'm not quite sure what the name of this type of butterfly is...i looked through my costa rica wildlife guide book and couldn't find him...but it was nice just watching him sit there and eat...i know the banana looks kind of nasty that he's eating, but, hey, to him i'm sure it's just delicious...for some reason the butterflies prefer spoiled or rotten fruit, they can't seem to get enough of the stuff. . . a lot of the birds prefer the fruit to be more on the ripe side as well.
