I will bet you would never have thought about this in a million years although, once I tell you the answer, perhaps it is rather obvious. A butterfly keeps its wings only in the biggest part of its body; the wings!
|Blue Morpho Butterfly|
Scientist believe that the butterfly would need such expert ears as it is perhaps essential to the survival of the insect, specifically in figuring out how and whne birds are going to attack. Lower pitch sounds would indicate the flapping of bird wings which would signal the butterfly to turn tail and run, however higher pitch sounds, like that of bird song would indicate to the butterfly that the bird has probably not spotted it yet thus eliciting the butterfly to remain at rest or stay extremely still, a posture which keeps most butterflies expertly hidden.
