Butterflies are great animals, a great loss if we didn't have them, but did you know that they aren't all smiles and sunshine?

Butterflies threaten each other in Morse code. Scientist heard blue and white longwings make clicking sounds when they confronted a new species of butterfly. They also use it to communicate to other butterflies of the same species.

Caterpillars are just as talented as they can tapdance. They dance on leaves, stamping their feet when scared so as to attract ants which can protect them.

Just to add some references to this fascinating stuff :)

Philip DeVries, an entomologist at the University of Texas, has studied this example of caterpillar-ant symbiosis in Panama. With the aid of a sensitive microphone, he has produced the world's first recording of caterpillar 'song' - or dance (Science, vol 248, p 1104).

Torpid peacock butterflies (Inachis io) produce intense ultrasonic
clicks that startle captive vespertilionid bats {Plecotus auritus and Pipistrelhis pipistreUus). The clicks occur as the wings are opened and are generated by a stiff portion of wing membrane between the costal and subcostal veins near the base of the forewing. The power spectrum of a click matches the most sensitive area of a bat's audiogram. Clicks may serve as acoustic equivalents of the attack-retarding eyespot display in the same species.

Unless someone has taught them a Latin alphabet I sincerely doubt this.

quite interesting fact of the monarch butterfly (the ones here in south africa anyway)is that male sometimes forces sexual relations on a would be mate. Some texts have quoted it as 'rape' while others with a more "if its nature there must be a hidden meaning" inclination have suggested it is the females method of determining fitness of the suitor!

A butterfly house breeder and owner I know has, for years, made use of catterpiller memories by making sure her catterpillers are handled & fed by visitors when they visit. As a result her butterflies seek out company and will happily perch and interact with guests. :-)
