, 1 sec f/18.0, ISO 100, tripod. Specie: Zerynthia polyxena

La Polissena (Zerynthia polyxena (Denis & Schifferm?ller, 1775)) è un lepidottero diurno appartenente alla famiglia Papilionidae (famiglia prevalentemente tropicale, di cui solo 9 specie presenti in Italia), con apertura alare di 50?60 mm. Visione dorsale I bruchi si nutrono di varie specie di aristolochie, compiono 5 mute nell'arco di 4/5 settimane, dopo di che le crisalidi, legate ad un sostegno, svernano per sfarfallare nella primavera successiva. Gli adulti sono attivi per non più di tre settimane. La particolare alimentazione delle larve fornisce alle stesse sostanze tossiche, che passano poi anche alle farfalle adulte, rendendole incommestibili. La colorazione della livrea dell'adulto, gialla, con caratteristici disegni neri, rossi e blu, è detta "aposematica" (cioè "ammonitrice"), in quanto serve proprio a scoraggiare i potenziali predatori. In Italia, la farfalla è diffusa al di sotto delle Alpi più o meno fino all'altezza del Po. A lititudini inferiori si trova soprattutto l'endemismo italiano Zerynthia cassandra.
