South-West Wildlife: Yarrow Plume Gilleria pallidactyla

I found an area with quite a bit of Yarrow three weeks ago and have been keeping an eye on it to see if I could find Yarrow Plume Gillmeria pallidactyla. On the 21st I was pleased to find this moth nearby. There is sufficient information on the photo to eliminate Gillmeria ochrodactyla which would struggle to find the food plant in the area because it doesn't exist.
