An insect with two pairs of large wings that are covered with tiny scales, usually brightly colored, and typically held erect when at rest.
Also: a stroke in swimming in which both arms are raised out of the water and lifted forward together.
Trivial tidbit: Some butterflies and moths smell or taste with their feet. A butterfly was, at one time, called a 'flutterby.'
The main component is the handshape, two hands with two thumbs crossed, palmed in. The "x" symbol under the two hands is the cross at the wrists. The double lines outside the hands indicate how the hands move.
