Time-lapse video. This time lapse clip shows the expansion of the Blue Morpho butterfly. The fluid from the butterfly's body is pumped into its thread-like wing veins. Gravity holds the wings held straight as the fluid ripples through them. This is the only time an adult butterfly grows and it is all over in ten minutes. Afterwards the wings harden off over a period of hours.
