Abstract： The habits of adult Parnassius szechenyii Frivaldszky were investigated from June to August 2009 in the Qilian mountains, Qinghai province. The results show that this butterfly usually flies from above the middle of valleys to hilltops on windless, sunny and warm days, and avoids forest and human-modified environments. The capture sex-ratio was male-biased. P. szechenyii was most conspicuous in July during the breeding season between 12:30—13:00.
