description Nokomis Fritillary Overview

The Nokomis Fritillary (*Speyeria nokomis*) is a butterfly species native to the southwestern United States, particularly found in regions like Utah, Nevada, Arizona, and New Mexico. It exhibits significant sexual dimorphism, where males display bright, tawny orange wings, whereas females possess darker brown or blackish patterns with pale markings. The insect typically inhabits canyon bottoms, open meadows, and woodland edges at moderate elevations. Females lay their eggs on or near violets, which serve as the primary food source for the resulting caterpillars.
