I posted a shot of this Venezuelan butterfly before but now I've got a close up, and I've also got an ID for it. The simple but lovely Venusta Yellow (Pyrisitia venusta)
Notice the ocelli on the top of its head? They are the 3 black dome-shaped dots in a triangle between the compound eyes. They are also known as simple eyes, and are believed to detect only light and movement. See bee's ocelli on previous post
