JOURNAL FREE ACCESSA case of prolonged emergence of Samia cynthia pryeri (Butler, 1878) was reported. The overwintering generation of this species was collected in Yasu City, Shiga Prefecture, Central Honshu, as mid-instar larvae on September 10th, 2016. The larvae were estimated to be a brood, because they were found in a single host tree as a group, being the same larval instar. All of the 16 larvae pupated in a period from 20th to 24th in September. They were transferred in a large rearing cage (60× 56×94 cm) indoors for emergence in the next summer. The room was maintained in semi-natural air and light condition without any air conditioning equipment. Nine (1♀8♂) overwintering pupae emerged in a period from 7th to 23rd of June, and four (2♀2♂) in a period from 2nd to 19th of August in 2017. The adult moths usually fly twice a year in Shiga Prefecture, though this species is univoltine in Kanto region and northern area in Japan. The prolonged emergence observed in this time, with almost a bimodal pattern, suggests that this species could take a flexible strategy under a variable environment in the Central Honshu.
