¡Muchas Gracias, Gerardo! Todo un cumplido para mí. :-)

Wonderful series :)

Thank you Mayra!

Wow! Wonderful!!!

Jolly and Sérgio-- Thank you very much‼ I really appreciate your help.

Walter, this part of the wing that looks like antennae are a mechanism of defense of the butterfly. With these protrusion in the wings and with the ocelli this kind of butterflies confuses predators , specially birds. So the birds can see like another butterfly. This kind of butterflies are very vulnerable while they are feeding, so they don´t open the wings, they only rub a wing against the other. In Argentine we use the term 'frotadora' for these kind of butterflies. Here some links:

In the USA occurs Calycopis cecrops, similar to this one.

I looked at your spotting, asergio -- very cool! I wonder whether there are similar looking butterflies in North America (USA).

Geodialist, these butterflies have this unique wing shape which mimic antennae. Its purpose probably is to deceive predators. Attacking the rear of the wing, they would spare the vital parts of the butterfly. Here is another butterfly with this type of tail:

Perhaps you should add this spotting to the mission, "Mimetic Animals of the World." http://www.projectnoah.org/missions/8015...

Well, it sure fooled me! Thanks, Jolly!

Beautiful spotting Daniela.

The protrusion you see at the rear of the butterfly is just to fool predators to think that the head is there. It is a survival camouflage.

OK, can you tell me what I'm seeing on the other end of the butterfly that appears to be another pair of antennae?

¡Mucha Gracias, Sérgio!

Hi Walter, is the same butterfly. There was only a butterfly in that leaf.

Belissima série, Daniela. Geodialist, there is only one butterfly in this series.

Is it safe to assume you realize this is a mating pair of butterflies?

Thank you Sukaina!

pretty..
I like the last pic.
