Western Steep Fritillary Butterfly
Common Name: Western Steep Fritillary
Order Name: Lepidoptera
Family Name: Nymphalidae
An early morning trek to a specific meadow in the Owens Valley of California provided a glimpse at this indigenous subspecies population of Western Steep Fritillary. The cool early morning mountain air slow down these beautiful fritillary butterflies as they sip nectar from thistles. These butterflies exhibit sexual dimorphism meaning the male and female butterflies look different. This orange form is the male and was abundant in comparison to the black and yellow-green females. Caterpillars feed on blue violet and over winter shortly after hatching. Adults have a single brood each year and fly from June to September.
