A male papilionid butterfly, Graphium doson, was collected in Ikeda City, Osaka Prefecture, Japan. This may be the first recorded instance of this species in the northern part of Osaka. It is believed that this species has expanded its distribution northeastward from the Chugoku or Shikoku districts to Osaka Prefecture, possibly due to climate warming and an increase in host tree planting.
