A Common gray moth of the family Geometridae. These lovelies live in North America from Mexico to Alaska and do a wonderful job at camouflage. While not a perfect hiding spot, this fellow has chosen to settle in for the evening on a young yellow cedar tree, Chamaecyparis nootkatensis, in Vancouver's city-owned Stanley Park.
The thin, greyish-brown and scaly bark provides a pretty good cover. He was caught unawares and photographed beautifully by the hugely talented, Dan Bowden, on one of his recent visits to the city.
