Status: Breeding stray
NENHP Ranking: Not listed
Range: This is an overwintering resident in southeastern and southwestern United States, with strays ranging north to New York, Wisconsin, Nebraska and Utah. In Nebraska this species has been recorded from the southern half of the state.
Broods/Flight Times: Found in Nebraska from mid-May to early October
Larval Hostplant(s): Pipe Vines – (Aristolochia species). These plants do not normally survive winters this far north on a consistent basis, but with care some are nurtured as ornamentals.
Habitat: As a stray they may occur anywhere
Overwintering: As pupae, although they cannot survive Nebraska winters.
