Description:
Note: This species is listed with the genus name Chalceria
by some authors. Ferris’ Copper (Lycaena ferrisi), previously
included as a subspecies of L. rubidus, is a newly described species
nearly identical in appearance and ecology to the Ruddy Copper, and occurs only
in the White Mountains of Arizona and New Mexico.
Range:
This species ranges from southern British Columbia and Alberta south through
the northwestern U.S. to central California, eastern Arizona, and northern New
Mexico, and east as far as western North and South Dakota and Nebraska. It occurs
through much of Idaho.
Habitat:
It occurs in open areas such as sagebrush steppe, prairies, fields, and along streams.
Diet:
Caterpillar:
Caterpillars feed on various species of dock (Rumex spp.).
Adult:
Butterflies drink flower nectar, most frequently from shrubby cinquefoil
(Potentilla fruticosa).
Ecology:
Eggs overwinter and hatch in the spring, and the resulting brood is the only generation of caterpillars each summer. Each caterpillar undergoes four stages of growth, called instars. Adults generally fly from the end of May to the beginning of September. Butterflies are swift fliers, and may pursue each other.
Reproduction:
Males perch to wait for receptive females. Females lay eggs singly at or near the bases of host plants.
Conservation:
Idaho Status: | Unprotected nongame species. |
Global Rank: | G5; most populations are widespread, abundant, and secure. Ferris’ Copper, however, is ranked T1, which means it is critically imperiled because of extreme rarity and is imminently vulnerable to extinction. |
