This geometrid moth seems very variable and in some of the photos that I found, the black stripes are not nearly so distinct. It flies in the autumn and the colours could be mistaken for leaves that have turned. This species of moth, Tetracis jubararia is found in western North America was far east as Saskatchewan. The larva feed on a variety of deciduous shrubs and trees including willows, alders, birch and dogwood and mimic twigs.
Two biologists on a beautiful property armed with cameras, smart phones and a marginal knowledge of websites took up the challenge of documenting one species a day on that property. Join along! Posts and photographs by Leah Ramsay and David Fraser (unless otherwise stated; started January 1, 2014.
