|Finally, after five years of strenuous pursuits, I was able to re-shoot this species, which is quite common but that is really elusive and lives just a couple of months a year, in this spring. This is the female, I hope to also capture the male before they disappear.|
Species: A. cardamines
The Orange Tip (Anthocharis cardamines) is a butterfly in the Pieridae family.
So named because of the male's bright orange tips to his forewings. The males are a common sight in spring flying along hedgerows and damp meadows in search of the more reclusive female which lacks the orange and is often mistaken for one of the other 'White' butterflies. The undersides are mottled green and white and create a superb camouflage when settled on flowerheads such as Cow Parsley and Garlic Mustard Alliaria petiolata. The male is able to hide his orange tips by tucking the forwings behind the hindwings at rest. If you look closely at the mottling you will see that the green colour is in fact made up of a mixture of black and yellow scales. It is found across Europe, and eastwards into temperate Asia as far as Japan. The past 30 years has seen a rapid increase in the range of the Orange Tip in the UK particularly in Scotland and Ireland, probably in response to climate change.
The female lays eggs singly on the flowerheads of Cuckooflower Cardimine pratensis and Garlic Mustard and many other species of wild Crucifers, all of which contain chemicals called glucosinolates. Females are attracted to larger flowers, such as Hesperis matronalis, even though some such species are poor larval hosts. Selection of foodplants is triggered by the presence of mustard oils, which are detected by chemosensory hairs on the fore-legs (is this really true? or is it glucosinolates that are stimulatory? This contributor has not been able to find a reference for the statement of a stimulatory effect of mustard oils). Reproductive rate of females appears to be limited by difficulties in finding suitable hosts. As a consequence, the species has evolved to use a wide range of crucifers. The eggs are white to begin with but change to a bright orange after a few days before darkening off just before hatching. Because the larvae feed almost exclusively on the flowers and developing seedpods there is rarely enough food to support more than one larva per plant. If two larvae meet one will often be eaten by the other to eliminate its competitor. Newly hatched larvae will also eat unhatched eggs for the same reason. To stop eggs from being laid on plants already laid on the female leaves a pheromone to deter future females from laying. There are five larval instars. The green and white caterpillar is attacked by several natural enemies (notably Tachinid flies and Braconid wasps). Pupation occurs in early summer in scrubby vegetation near the foodplant, where they stay to emerge the following spring. Recent research suggests that the emergence of the butterfly may be delayed for as much as two years, thus ensuring the species against unfavourable conditions in a given season. Some Orange Tip may be confused with moths.

Anthocharis cardamines (Linnaeus 1758) Aurora
Farfalla di medie dimensioni (apertura alare 40-50 mm) dalla colorazione di fondo bianca. I maschi evidenziano la metÃ esterna delle ali anteriori di un vivace colore arancione, mentre le femmine presentano solamente una bordatura apicale nera e margine esterno molto arrotondato. Le ali posteriori mostrano nei due sessi disegni verdastri con spolverature gialle.
Il suo ciclo biologico mostra una sola generazione primaverile. La crisalide, svernante e di tipo succinto, appare inconfondibile per via della forma carenata e per un prominente processo cefalico. I bruchi, verde pallido o verde bluastro dorsalmente e biancastri lateralmente, si nutrono di Crucifere (gen. Cardamine, Sisymbrium, Sinapis ecc.) sulle quali si mimetizzano confondendosi con le silique.
Distribuzione ed ecologia
Presente in gran parte dell'Europa, salvo Iberia meridionale e Scandinavia settentrionale. In Italia la si ritrova abbastanza comunemente fin quasi i 2000 m. Nel circondario si riscontra con maggiore frequenza in eucalipteti e radure boschive.

Congratulations on finally capturing this fine shot of the Orange Tip butterfly. At first glance I thought it was a Cabbage white until I took a closer look at its wing markings. Very unique pattern and colors make it easier to them them apart.
Focus is sharp and colors well saturated, yet natural in appearance. The exposure is perfect. TFS.
Patience one of the qualities of the photographer, beautiful macro of this butterfly,
fine POV and the way it is framed with the background leafs, excellent focus, sharpness, details, TFS
Ciao Luciano, gran bella femmina, questa fa dimagrire per Beccaria, comunissima, ma la prima volta che l'ho fotografata ci ho fatto qualche chilometro, ottima resa del bianco e splendidi dettagli, nravissimo, buona Pasqua, ciao Silvio
I think I have seen this species here but due to perfect lens (my 70-300mm which I used for butterfly picture not working any more) I can't take butterfly picture now a days.
Although you didn't get such stunning POV but what you got you captured it well. Well sharp picture and yes, exposure on white wing looks good.
Thanks for sharing,
Regards and have a nice Easter,
Les fleurs et les feuilles aident au cadrage du papillon. La prise de vue permet de voir les dÃ©tails du papillon Aurore. La bonne luminositÃ© fait ressortir les couleurs. Bonne soirÃ©e.
