Arctia yarrowii, or Yarrow's tiger moth, is a moth of the family Erebidae. It was described by Richard Harper Stretch in 1874. It is found in North America from Hudson Bay to British Columbia and northern Arizona.[1] The habitat consists of barren rocky fellfields and slides above the timberline. These moths are also found in the Pacific Northwest.[2]
The length of the forewings is about 22 mm. Adults are on wing from mid-July to mid-August.[3]
The larvae probably feed on various herbaceous plants.[4]
This species was formerly a member of the genus Pararctia, but was moved to Arctia along with the other species of the genera Acerbia, Pararctia, Parasemia, Platarctia, and Platyprepia.
