Species: P. c-album
The Comma (Polygonia c-album) is a species of butterfly, common in the United Kingdom and with a distribution across Europe and temperate Asia to Japan and south to Morocco. Similar species are found in the United States and Canada. It has a white marking on its underwings resembling a comma. The wings have a distinctive ragged edge, apparently a cryptic form as the butterfly resembles a fallen leaf. The caterpillars are also cryptic, resembling a bird dropping.
In the 19th century the British population of comma butterflies crashed, and by 1920 there were only two sightings. The cause for this decline is unknown, and from about 1930 the population recovered and it is now one of the more familiar butterflies in Southern England, and is now resident in Scotland and in North Wales.
The caterpillars will feed up on hops, and they will also eat stinging nettle or elm or currant leaves, and in other parts of its distribution (e.g. in Sweden) also sallow and birch leaves.
The species survives the winter in the adult stage, and adults are of two forms. The form that overwinters before reproducing has dark undersides of the wings, whereas the form that develops directly to sexual maturation has lighter colured wing undersides. Both forms can arise from eggs laid by the same female, depending mainly on the photoperiods experienced by the larvae, but also with an influence of host plants, temperature and sex of individuals.
La vanessa c-bianco deve il suo nome al curioso disegno a forma di c nella pagina inferiore delle ali. E' caratterizzata da un colore fulvo a macchie più scure. Vive in ambienti con fiori ai margini dei boschi e dei giardini

Beautiful photo of this Comma. Excellent sharpness and fantastic camouflaged colors. Taken from an attractive low POV.

It is the nature that it gets invisible to ones naked eye, there by looking at we define in our mind the out lines and create that image.
The detailed NOTE makes this more visible and fair, it is well exposed shot, well done.
Ciao Luciano, bell'esempio di mimetismo, mica facile vederlo, gran macro con splendida nitidezza e ottimi dettagli, bravissimo, ciao Silvio

This butterfly is really a master of camouflage. It is easy to conffuse it with the litter.
Amazing camouflage indeed...Polygonia c-album looks like a old leaf...
Great camouflage of this species of butterfly, fine low POV,
excellent focus, sharpness, and details, TFS
La végétation aide au cadrage de l'insecte. La prise de vue permet de voir les détails du papillon Robert-le-Diable. La lumière donne de belles teintes aux couleurs de l'image. Bonne journée.
