Our summer fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America online and free. If everyone who uses this resource makes a donation, we could cover our ongoing costs, develop new features, upgrade the system, and maybe even remove those pesky ads. Please make a one-time or recurring donation to show your support for this valuable source of information. Thank you!
Identification: "Apamea acera is the only large ash-gray Apamea in North America. Usually, there is some orange shading around the orbicular and reniform spots. The basal dash is sharply defined in black and frequently extends almost to the postmedian line. The claviform spot is also outlined in black and extends about 3/4 of the distance to the postmedian line. The transverse lines are obscure."
Wing Span: 4.0-5.0 cm
Flight: mid-June to Mid-October
Habitat: Montane forests
Range: Northwestern U.S. and southern British Columbia, south to the San Bernardino Mountains in southern California. Also disjunct populations in eastern Nevada and Utah.
National Moth Week was July 23-31, 2022!
Moths are amazing creatures. Take photographs and share your moth sightings with us to document the moths where you live. Learn more.
