| Speyeria aphrodite manitoba (F. & R. Chermock, 1940) Speyeria aphrodite alcestis (W. H. Edwards, 1877) |
| Status: This species is a resident in Nebraska where it is locally uncommon to common in the west and rare (possibly extirpated) in the east. |
| Flight Period(s): There is one flight in Nebraska where it has been recorded from 11 May – 25 August. |
| Range: With the exception of the westernmost states and provinces, this species occupies roughly the southern half of Canada and the northern half of the United States. In Nebraska is currently occupies the panhandle and has, in the past, been found scattered through much of the rest of the state. |
| Larval Hostplant(s): Various Violets have been documented, of which the Yellow Prairie Violet (Viola nuttallii) and Viola nephrophylla occur in the state. |
| Overwinter: As unfed caterpillars |
| Commentary/Habitat: This butterfly has been found in the state as two rather distinct subspecies. Western Nebraska populations are somewhat variable but appear to be closely alligned to the high plains subspecies manitoba. Subspecies alcestis (found north and east of the state) was apparently widespread in eastern Nebraska in the past but has not been recorded since Steve Spomer found one in Lancaster County in 1978. |
| Similar Species: Other Fritillaries, especially Speyeria cybele |
