|scientific name Speyeria mormonia |
common name Mormon Fritillary
Mountain meadows and prairie grasslands.
One flight, peak emergence ranging from early July to mid August depending on elevation.
This fritillary is the smallest of the genus (wingspan 40 - 50 mm), and it's small size, orange upperside ground colour and straw and green underside are good diagnostic characters.
This is a variable species, and alpine populations tend to be darker ventrally and dorsally. Subspecies eurynome is the name associated with Alberta populations.
The larvae are black and spiny, typical of the genus. There are two pale yellow dorsal lines (Guppy & Shepard 2001). The Mormon Fritillary is equally at home on dry prairie and alpine and subalpine meadows.
Not of concern.
Larvae reportedly feed on violets (Guppy & Shepard 2001), although some mountain populations may use other plants where violets are not available (Bird et al. 1995).
AK south to CA, NM, and AZ (Scott 1986), east to southwestern Manitoba (Layberry et al. 1998).
