Habitat and Range
Geographic Range
British Columbia south to Kern Co., California and eastward to western Montana, SE Idaho, Carbon Co., Wyoming, and Larimer Co., Colorado, from 2600–7800’ (790-2375m)
Seasonal Activity
Adults fly as early as February into June, with female stragglers into mid-July
Diet and Behavior
Diet: two confirmed hosts in northern California for cervinaria are Prunus emarginata and P. virginiana , Ferris and Schmidt, 2010. Older information indicates larvae may also feed on leaves of alder, Bitterbrush ( Purshia tridentata ), cascara, Ceanothus species, Madrone ( Arbutus menziesii ), manzanita ( Arctostaphylos spp.), willow
Life History
one generation per year; overwinters as an egg

Species notes from the sources
Etymology: CERVINARIA: perhaps from the Latin "cervinus", from "cervus" (a deer), although I can't guess what association the moth has with a deer or the deer family; any ideas appreciated
About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Tetracis cervinaria. Species-specific details appear above.
Group overview
Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.
Ecological role of the group
Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.
Economic and practical significance of the group
Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
