occurs (regularly, as a native taxon) in multiple nations
Comments: Deciduous or mixed forest or woods very often near alders along streams or in hillside beech stands; alder swamps, occasionally shaded suburban settings. Often forms transient colonies. Like most forest butterflies often seen on dirt roads.
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.
In some part of its range at least in recent decades very sporadic and/or transient. For example in and near Cumberland-Cumberland Counties NJ absent from sometime before 1989 through 1994, frequent and widespread summer of 1995; absent 1996-2000. Very likely is declining in some regions. Speculations that decline is caused by exotic Coccinelids is very reasonable but not proven.
Adults feed from a variety of sources including APHID HONEYDEW, SAP CARRION MUD AND DUNG BUT NOT FLOWER NECTAR. Males both perch and patrol for females (Scott, 1986).
Degree of Threat: D : Unthreatened throughout its range, communities may be threatened in minor portions of the range or degree of variation falls within natural variation
