General Description
[From Ferris and Brown 1981; Scott 1986; Opler and Wright 1999; Glassberg 2001; Pyle 2002] Forewing 3.1-4.4 cm. Uppersurface bright orange overall (resembles the Monarch, Danaus plexippus), white spots in black marginal bands on both wings and subapical black triangle on forewing, veins black, black postmedian line crossing dorsal and ventral hindwing perpendicular to black veins.

Phenology
One flight in the far north, June to July; two flights in northern US, mostly June and August; four or more flights in the south, spring to fall (Scott 1986). April to October in the south, mainly June to August or September in the north (Glassberg 2001). Mid-May to early October in Colorado (Scott and Scott 1978), early April to late September in Oregon and Washington (Pyle 2002), mid-May to late September in Oregon (Warren 2005), May to August in British Columbia (Guppy and Shepard 2001).

Diagnostic Characteristics
Best determined by combination of uppersurface bright orange overall, black wing margins with white spots, black postmedian line crossing dorsal and ventral hindwing perpendicular to black veins.

Range Comments
Northwest Territories south and east of the Cascade and Sierra Nevada mountains to central Mexico except high mountains and arid lands away from water, east through southern Canada and the eastern US (Scott 1986; Oppler and Wright 1999; Glassberg 2001; Pyle 2002); to 2362 m elevation in Colorado (Brown 1957; Scott and Scott 1978), to 915 m elevation in Oregon (Warren 2005). In Montana, reported across much of the state (Kohler 1980; Stanford and Opler 1993). Uncommon to common east of the Rocky Mountains, locally rare west of the Rocky Mountains (Glassberg 2001).

Migration
Non-migratory; individuals may disperse 2-3 km (Nelson 2003).

Habitat
Watercourses, lake edges, riparian areas, willow thickets, valley bottoms, wet meadows, roadsides, deciduous woodlands (Ferris and Brown 1981; Scott 1986; Opler and Wright 1999; Glassberg 2001; Pyle 2002). Habitat in Montana not described but probably similar.

National Vegetation Classification System Groups Associated with this Species

Food Habits
Larval food plants include Amelanchier, Betula, Chrysobalanus, Crataegus, Malus, Populus (several species), Prunus, Pyrus, and Salix (several species) (Scott 1986, 1992; Warren 2005). Adults feed on flower nectar (including Asclepias, Bidens, Cleome, Echinacea, Polygonum, Tamarix), aphid honeydew, sap, moisture from rotting wood and fungi, dung, puddles and mud (Downes 1973; Scott 1986, 2014).

Reproductive Characteristics
Females lay eggs singly, preferably on uppersides of host plant leaf tips (Scott 1986). Eggs hatch in about 6 days (depending on temperature), Larval development from L1 to L5 instar and pupa in about 24 days post egg-hatch, adults eclose (emerge from pupae) in about another 12-16 days (James and Nunnallee 2011). Larvae tend to feed at night, build nest from rolled host plant leaf only during hibernation, L3 instar (rarely L1 or L2) overwinters (Scott 1979, 1986; James and Nunnallee 2011). Males perch 1-2 m above ground on vegetation awaiting passing females, also patrol throughout the day along streams near host plants in search of females (Scott 1975b, 1986).
