|scientific name Lycaena hyllus |
common name Bronze Copper
Wetland edges, moist meadows, and sedge fens where dock (Rumex) grows.
One annual brood, the flight peaking in mid July to early August.
The large size (wingspan generally 30 to 38 mm) and bright orange, black-spotted forewing underside will distinguish the Bronze from other coppers. There are no named subspecies.
The eggs, which hibernate, are white or greenish white (Scott 1986). The larva is yellowish green with a dark dorsal stripe (Layberry et al. 1998), and pupae are light brown with dark dots (Scott 1986). The adults perch on tall grasses and sedges (males wait for females), and colonies tend to be localized in distribution.
Not of concern.
The larvae feed on a number of species of dock (Rumex spp.), and are usually associated with Rumex crispus, and possibly also feed on smartweed (Polygonum coccineum) (Bird et al. 1995).
Occurs from the southwestern Northwest Territories south to New Mexico and Oklahoma, east to the Atlantic seaboard. Absent from the western Mountains (Opler 1999).
