Description:
Note: This species is listed with the genus name Gaeides by
some authors. Some authors consider this species to be a subspecies of Lycaena
xanthoides, the Great Copper.
Range:
This species ranges in Canada from southern Alberta east to southern Manitoba,
and in the U.S. from northern Idaho east to Minnesota, extending south to northern
Texas and central Missouri and Illinois. In Idaho, it has been documented only in Bonner County.
Habitat:
It occurs in open, grassy areas, such as fields, prairies,
meadows, and marshes.
Diet:
Caterpillar:
Caterpillars feed on the leaves of a variety of docks (Rumex spp.).
Adult:
Butterflies drink flower nectar, often from milkweed (Asclepias spp.)
and thistle (Cirsium spp.).
Ecology:
Eggs overwinter and hatch in the spring, and the resulting
brood is the only generation of caterpillars each year. Each caterpillar undergoes
four stages of growth, called instars.
Adults generally fly
from mid-May through July or August. Butterflies exhibit a fast and erratic
flight pattern, can be aggressive towards other butterflies, and are most active
in the afternoon. They tend to stay in the same general location during their
lifespan.
Reproduction:
Males perch to
wait for receptive females. Females lay pale green eggs singly at or near the
bases of host plants.
The eggs turn white before hatching.
Conservation:
Idaho Status: | Unprotected nongame species. |
Global Rank: | G5; populations are widespread, abundant, and secure. |
