Swallowtail butterfly coaster

This design was created with reference to the "Ageha-cho crest pattern diagram and training text" found in "Kyoto Crest Uwa-e-shi" in "Japan Crest Grand Illustrated Book" on March 28, 2013. The term "lying butterfly" refers to a state where the wings are held horizontally, whereas "raising the wings" or "ageha-cho" refers to a state where the wings are raised and stationary. The "ageha-cho" that appears in family crests is not generally the same as the swallowtail butterfly. It was surprising to learn that the ageha-cho in patterns and the swallowtail butterfly in biology are different. It was also surprising to discover that the name of the pattern is distinguished by whether the wings are raised or lowered. (From "Exploring Family Crests" by Keiichi Morimoto)
