|scientific name Lycaena helloides |
common name Purplish Copper
Moist meadows, wetland edges and weedy places where docks (Rumex) grow.
Two broods per year, flying mid to late June and again in August.
The Purplish and Dorcas Coppers can be difficult to distinguish; The Dorcas Copper is slightly smaller, usually with a wingspan of 25 mm or more (23 to 33 mm). The orange band on the hindwing upperside is reduced in Dorcas, and the dark border of the forewing is wider. The forewing shape is not as pointed a sit is in helloides. Females of helloides have more orange on the upperside.
The egg is white and round, the top and bottom slightly flattened; it is the overwintering stage of the second generation (Guppy & Shepard 2001). The mature larva is apple green with a yellow lateral line and light brown head. The pupa is initially green, turning brown as it ages (Guppy & Shepard 2001).
Not of concern.
The larvae feed on docks (Rumex spp.) and knotweed (Polygonum spp.), both member of the family Polygonaceae (Layberry et al. 1998). Adults mud-puddle and visit flowers (Hooper 1973).
Southern Ontario west to southern BC, south to Californnia, New Mexico and the western Great Lakes States (Opler 1999).
