Vanessa cardui is a well-known colourful butterfly, known as the Painted Lady, or in North America as the Cosmopolitan. This butterfly has a strange pattern of flying in a sort of screw shape. V. cardui is one of the most widespread of all butterflies, found on every continent except Antarctica and South America. In Australia, V. cardui has a limited range around Bunbury, Fremantle and Rottnest Island. However, its close relative, the Australian Painted Lady (Vanessa kershawi, sometimes considered a subspecies) ranges over half the continent. Other closely related species are the American Painted Lady (Vanessa virginiensis), and the West Coast Lady (Vanessa annabella). Vanessa cardui occurs in any temperate zone, including mountains in the tropics. The species is resident only in warmer areas, but migrates in spring, and sometimes again in autumn. For example, it migrates from North Africa and the Mediterranean to Britain in May and June, but having produced offspring they then die in the Autumn. Vanessa cardui butterflies are raised in many pre-school classrooms to demonstrate the life cycle of a butterfly. Naturally, this is one reason they are so popular amongst children. They are also often found in science fair projects. The egg takes 3 to 5 days to hatch. The eggs are tiny, as tiny as a sugar crystal. They are green and can be observed best with a magnifying glass. The caterpillar takes 711 days to turn into a chrysalis. At this stage the caterpillar eats a great deal of mallow and other types of plants. Before entering its chrysalis, the caterpillar will moult several times because of how quickly it grows in such a short period of time. The moult appears as a black speck, what looks like dirt, near the caterpillar. Many people believe this to be the excretion of the caterpillar, but it is truly the moult (the skin the caterpillar has grown out of). It takes 711 days for the chrysalis to turn into a butterfly. The painted lady butterfly travels around 1000 miles in its life. Its wing span is 2 inches. The painted lady caterpillar is black with spiked skin. Larvae feed on Asteraceae spp., including Cirsium, Carduus ,Centaurea, Arctium, Helianthus, and Artemisia spp.


La Vanessa del Cardo (Vanessa cardui) una farfalla della famiglia delle Ninfalidi. diffusa in tutti i continenti ad eccezione dell' Antartide. In Australia invece ha una diffusione limitata a poche aree della zona occidentale, tuttavia il suo parente stretto, la Vanessa kershawi, talvolta considerata una sottospecie, diffusa in buona parte del continente. La specie solita passare gli inverni solo nella fascia tropicale e a volte nelle aree meridionali del Mediterraneo pi calde (ad esempio in Sicilia), ma in primavera, e talvolta nuovamente in autunno, migra. Ad esempio la vediamo spostarsi dal Nord Africa e dal Mediterraneo all'Europa meridionale e centrale fino ad arrivare alla Gran Bretagna nei mesi di maggio e giugno. L'uovo si schiude da 3 a 5 giorni dalla deposizione. Il bruco, di colore nero, impiega da 7 a 11 giorni per trasformarsi in una crisalide. necessario un tempo analogo per passare dallo stadio di crisalide a quello finale di farfalla. A metamorfosi avvenuta non rimane in una stessa zona a lungo: nella sua vita vola per oltre 1000 miglia. La sua apertura alare di 2 pollici. Il bruco si pu nutrire di una vasta gamma di piante della famiglia delle Asteraceae, prediligendo i generi Carduus (Carduus crispus) e Cirsium (Cirsium arvense), ma a volte ospitato anche da Boraginaceae, Malvaceae come la Malva neglecta, e poche Fabaceae.
Gli adulti prendono il nettare da molti fiori di campo (tra le preferite il Carduus) e da alcune specie di piante da giardino come girasole, Buddleja spp., Aster spp. e Zinnia spp.


Lunghezza ala anteriore:26-33 mm
Distribuzione in Italia: tutta Italia isole comprese.
Habitat: specie migratrice, frequenta ogni tipo di ambiente dal piano basale a quello montano e cacuminale, sino a oltre 2000 metri s.lm.
Generazioni annuali: gli individui migranti che raggiungono l'Italia si riproducono in genere due volte, dando luogo ad adulti in giugno-luglio e settembre ottobre.
Piante nutrici: Cisium vulgare - Urtica dioica - Sympphytum tuberosum.

Hi Roberto.
I think the better POV and butterfly pose are absent. Great wingspread, superb isolation of the butterfly from natural BG, impressive combination of smoothness of the BG and tack sharp details of the main subject. TFS and kind regards.
Alexei.

Ciaao Roby,
Beautiful macro as always from you - excellent lights, colors and nice shallow depth of field to isolate the subject. Although the antennae and the right wings are very sharp, the left aren't... Otherwise a fascinating photo.
Best regards, Lszl
