Colias sent on July 13, 2015 (18:38) by Raffaella Coreggioli. 25 comments, 1778 views.

, 1/6 f/13.0, ISO 100, tripod. Specie: Colias crocea

Colias crocea (Fourcroy, Geoffroy 1785) Dimensioni Lunghezza ala anteriore mm. 23-27 Apertura alare: 46 - 54 mm Descrizione della specie: Queste farfalle hanno come colore dominante il giallo, arricchito da sfumature aranciate, più tenue per la femmina, più intense per il maschio. Si osserva ancora, nel maschio, un bordo nero nella parte terminale delle ali anteriori che continua anche nelle posteriori. Nella femmina al posto di questo bordo nero vi è una serie di piccole macchie scure disposte in fila in maniera crescente dal basso verso l'alto. In entrambi gli esemplari presentano un margine intero e convesso con due venature anali nelle ali posteriori. Si può confondere con C. alfacariensis e C. hyale, che però hanno meno nero nel bordo esterno delle psap. La femmina può essere della forma helice Hubner, con colore giallastro chiaro sulle ps anziché arancio. La parte inferiore delle ali anteriori ha macchie postdiscali scure ed aree discali e basali giallastre, mentre, sempre inferiormente, le ali posteriori hanno colore di fondo giallo-citrino con una macchia discoidale bianca contornata di rossiccio ed una serie di punti scuri nella regione postdiscale. Possono dare origine a ibridi nei luoghi dove C. erate è presente. Dimorfismo sessuale: la parte superiore presenta l'apice nero delle ali anteriori delle femmine chiazzato di giallo, mentre nei maschi l'apice è nero uniforme. Le femmine nel 5% dei casi assumono una colorazione di fondo biancastra (forma ?helice', gene legato al sesso). Maschio: colore arancio con ampia fascia submarginale nera attraversata da esili strie nervulari gialle. Sfumatura basale nerastra e macchia nera disco cellulare nelle anteriori. Posteriori ampiamente velate di nerastro dal quale emerge una macchia disco cellulare arancio vivo. Femmina: simile al maschio ma presenti alcuni spazi gialli nella fascia submarginale. Velatura nerastra delle posteriori più estesa. Nelle femmine è frequente la forma "helice" a fondo bianco giallognolo. Stadi giovanili: le uova vengono deposte sulla parte superiore delle foglie della pianta nutrice. Il bruco è colore verde scuro con una fascia subdorsale e una laterale di colore giallo affiancate da grosse macchie nere.. Sverna allo stadio di bruco. In primavera avviene la metamorfosi in crisalide, appuntita all'estremità cefalica. Piante nutrici del bruco: Fabaceae (Coronilla spp., Lotus spp., Vicia spp., Trifolium spp., Medicago spp., Melilotus spp.). Distribuzione e habitat: paleartica: diffusa in Europa centro-meridionale, Nordafrica ed Asia minore, è una specie migrante. Specie non minacciata. specie euricora e migratrice, si rinviene in ambienti aperti dal piano basale a quello montano e cacuminale fino a oltre 2000 metri s.l.m. Periodo di attività: sfarfallamento: da maggio a ottobre con più generazioni annuali. Migrante.

Excellent, see these beauties gives me a desire that you have no idea, from the beginning of the season I allowed myself only a paltry 2 outputs in Valtellina.

Raffaella, Raffaella these your macros are incredibly beautiful! I know you will not be amazed by writing that I very much appreciate the care that you put in representing the flower on which the butterfly rests. Very Good. Thanks.
Best wishes.

Hello Rob, always depends on what I get, if I want to have the entire subject in focus and covered by pdc or fuzzy selective, f13 is not too close to this kind of close-up photography, it also depends on the size and compliance insect I'm going to portray, there are many factors that affect the diaphragm, for example, I could stay here even f10-11 but I closed more to have the background livelier.
Thanks for your kind visit :)

Very beautiful and elegant this composition. Congratulations! Hello Aurora


Thanks Aurora, gentle :)


A greeting
Raffaella
