Butterflies are a class of trick based around the "basic butterfly". The hands are held close together in front of the spinner and the poi spin in opposite directions flat to the spinner so that the poi cross at the top and bottom of their circles. This move can be done behind the head, behind the back and extended to any number of moves; there are as many variations on the butterfly possible as there are for the weave. The name butterfly refers to its appearance when viewed from the front: The poi appear to be flapping horizontally like a butterfly's wings.
