Alternate Common Name: Forest Copper.
Note: This species is referred to with the genus name Epidemia by some authors.
This species ranges from southern Alaska south through British Columbia and Alberta, through the Pacific Northwest east to central Montana and Wyoming, and south into northcentral California. In Idaho, it occurs primarily in the northern and central sections of the state.
Preferred habitat includes forest bogs and openings.
While records are sparse, it is thought that caterpillars feed on certain members
of the heath family (Ericaceae), such as huckleberry (Vaccinium spp.)
or on plants belonging to the buckwheat family (Polygonaceae).
Adult: Butterflies drink flower nectar.
Eggs overwinter and hatch in the spring, and the resulting brood of caterpillars is the only one each year. Each caterpillar undergoes four stages of growth, called instars. Adults generally fly from July through September. It is not uncommon to observe large numbers of adults in a given area. The word "mariposa" is Spanish for "butterfly."
Males perch to wait for receptive females. The typical locations of oviposition are unreported.
