The Painted Lady (Vanessa cardui) is a well-known colourful butterfly, sometimes known in North America as the Cosmopolitan.It is one of the most widespread of all butterflies, found on every continent except Antarctica. 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).The Painted Lady 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 offspring produced there die in the Autumn.Painted Lady butterflies are popular for many pre-school and kindergarten classes to raise in schools to demonstrate the life cycle of a butterfly. Painted ladies are very popular with children. They are used in many science fair projects. Several insect distribution companies such as Insect Lore include Painted Lady caterpillars in their catalogue of live insects for ordering.The egg takes 3 to 5 days to hatch. The caterpillar takes 7–11 days to turn into a chrysalis. It takes 7–11 days for the chrysalis to turn into a butterfly. It doesn't stay in one area so long. The painted lady butterfly moves 1000 miles in its life. Its wing span is 2 in. The painted lady caterpillar is black with spiked skin.The caterpillars feed on a wide variety of host plants of the families Asteraceae, especially Carduus crispus (as implied by the species name cardui – Latin for "of the thistles"). Also, Boraginaceae, Malvaceae (especially hollyhocks and dwarf mallow Malva neglecta), and a number of Fabaceae are eaten. The adults drink nectar from a variety of wildflowers and cultivars, more commonly the favored thistle, butterfly bush (Buddleja), asters, Tickseed sunflowers (Bidens) and zinnias.

La Vanessa del cardo è farfalla di dimensioni rispettabili, raggiungendo una apertura alare di circa 60mm, ed è una delle più note e studiate in assoluto, non solo nella nostra fauna.
La sua fama è dovuta al fatto di essere una notevole migratrice che, grazie alla potenza del suo volo, può compiere degli spostamenti enormi; infatti, con l’esclusione del Sudamerica, si può rinvenire in tutto il mondo.Le sue abitudini la portano a frequentare soprattutto terreni incolti e prati fioriti, in località molto calde ed assolate, ma anche radure e margini dei boschi,come pure giardini e parchi urbani, sia in pianura che in montagna, fino al limite estremo della vegetazione.
La sua abbondanza è estremamente variabile di anno in anno, così che può essere da sporadica a molto comune, come avviene in alcune annate, in relazione ai flussi migratori.A seconda dei climi presenta una o più generazioni annue, dalla primavera alla tarda estate, e si riproduce anche alle nostre latitudini, tramite gli individui che giungono annualmente dalle zone più calde. I bruchi si nutrono di diverse essenze, con una spiccata predilezione per le Carduacee, nonché per le ortiche.

Hi Roberto,
I have used Neat Image, which you can download from the web, with luminance set at 80% to reduce noise in the background. I have also used the Blur Tool in Photoshop carefully to remove some small artifacts caused by general sharpening If you zoom in and look around the antennae and the purple flowers, you will see what I mean. Its just to make the image look smoother and a little less processed.
