Swallowtails are strong fliers.
Butterflies can only fly if their body temperature is above 86 degrees. Butterflies sun themselves to warm up in cool weather. As butterflies age, the color of the wings fades and the wings become ragged.
The speed varies among butterfly species (the poisonous varieties are slower than non-poisonous varieties). The fastest butterflies (some skippers) can fly at about 30 mile per hour or faster. Slow flying butterflies fly about 5 mph.
