Habitat and Range
Habitat
Forests, old-fields, with hostplant
Geographic Range
North America except the arctic (British Columbia to Newfoundland, and all of United States). , ,
Seasonal Activity
adults fly from April to September or until frost
Diet and Behavior
Diet: Covell states larval food is Red-osier Dogwood, Cornus sericea . ( 5 ) They likely have another hostplant, since the adults of this moth have been observed in the lower Piedmont (Durham County) of North Carolina, where C. sericea is not known. Other Cornus species are present in that area: C. florida, C. amomum, C. stricta, and C. alternifolia (rare). See Radford, et al., Manual of the Vascular Flora of the Carolinas . Handfield reports larvae feeding on Cornus stolonifera = sericea (Red-osier Dogwood) and C. alternifolia (Alternate-leaved Dogwood) in Quebec. Larry Line states larval food as Cornus florida (Flowering Dogwood) in Maryland.

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Hypena bijugalis. 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.
Recorded sources for this group: IUCN Red List, Xerces Society, USFWS, PNAS, WWF. Imported estimates may describe particular regions or reporting periods.
