Samia cynthia is a beautiful Saturniidae originary from south east Asia. It was imported in Italy for silk production and accidentally released in the wild. After that, a Samia cynthia population has established in north Italy. Until 2015, S. cynthia was commonly found on A. altissima trees. Since 2016, due to increased parasitoids combined to an unusual series of storms coinciding with their spawning period, the population has gone though a severe bottleneck.
This cocoons are F2 from wild collected in north Italy, Lombardia region. They will overwinter and hatch in spring 2021.
