White Mountain Fritillary

This small orange fritillary exists nowhere outside the Presidential Range alpine zone, where wind, cold, rock, and dwarf plants define survival.

The White Mountain fritillary is an alpine subspecies restricted to New Hampshire’s highest summits. Adults fly low over rock and tundra vegetation during a short summer window, while immature stages endure a long, severe season far above the forest.

Its tiny range makes recreation, collecting, trampling, warming temperatures, and changes in snow cover consequential. Alpine trails concentrate foot traffic for a reason. A responsible observer remains on durable surfaces, uses a long lens, and never pursues a butterfly across fragile vegetation.

Upper wing
Orange-brown wings carry dark spots and bars.
Under wing
Pale and rusty patterning can help separate similar fritillaries.
Flight
Adults stay low in wind and use brief calm, sunny intervals.
Geography
A credible record must come from the Presidential Range alpine zone.

Good to know

Several fritillaries look similar below treeline. Elevation and exact alpine habitat are part of the identification, and photographs should capture both wing surfaces when possible without pursuit.
