Nymphalis antiopa, known as the Mourning Cloak in North America and the Camberwell Beauty in Britain, is a large butterfly native to Eurasia and North America. See also Anglewing butterflies.
The deep brown upperside rimmed with blue spots and a powder-yellow margin is unmistakable. Spring specimens are flight-worn and are faded to maroon-brown with yellowish-white margins. The Mourning Cloak is remarakbly consistent in appearance across its vast North American range, and there are no recognized subspecies (Layberry et al. 1998, Guppy & Shepard 2001).
This species has a wide distribution throughout the northern hemisphere, occuring from Great Britain across Eurasia and from Alaska south to central Mexico (Opler 1999).
Found in virtually all habitats throuhgout the province, particularly near moist and riparian woods.
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.
