Calephelis borealis
Northern Metalmark
Calephelis borealis, the northern metalmark, is a small butterfly in the family Riodinidae endemic to the eastern United States. It is one of few tropical-associated riodinids found in eastern North America. The species has declined across its range due to habitat loss from afforestation and invasive plant encroachment. Active management including canopy thinning and invasive plant removal has been shown to increase local populations.
