Malheureusement, je ne parle pas bien la Francais... Very nice image, but you may be surprised to hear that it is not a papillon (= butterfly) but a moth (in French, heterocere). It belongs to the Arctiidae ("Tiger Moths") which are often brightly coloured as a warning to birds and other predators that they are distasteful.

For me, this image has a bit too much shadow and is too close cropped. I think I would have liked it more, if there were more of the background and a bit more focus.

It is a nice shot, with good perspective, but the lighting could be better.
