Hodges Number
9785
Other Common Names
Sunflower Seedcopper (caterpillar) (1)
Synonyms and other taxonomic changes
Stiria rugifrons Grote, 1874
Explanation of Names
Specific epithet rugifrons is Latin meaning "creased face (frons)." Describing Stiria Grote notes that the genus has a remarkable clypeus that "exceeds the eyes" with a "heart-shaped, naked depression." (73)
Size
Wingspan 32-42 mm (2)
Larva less than 35 mm (1)
Range
Southern Saskatchewan and Alberta, Wyoming, Colorado and west Texas. Southern Ohio and Virginia south to northern Florida. (2) Indiana and Kansas. (3) Range does not overlap with southwestern S. intermixta. (4)
Food
Sunflowers including small woodland sunflower (Helianthus microcephalus) and Porter's sunflower (Helianthus porter). Likely others. (2) (1)
Life Cycle
Larva; larva; larva; adult
Remarks
"Stiria rugifrons and intermixta are extremely close morphologically and superficially. Stiria intermixta may be just the southwestern US Mexican race of rugifrons. The ranges of variability in both the male and female genitalia overlap and cannot be used to separate the two species consistently." (5)
See Also
Stiria dyari - lacks dark basal patch. Limited to southern Nevada, southern California and Baja California.
Stiria intermixta - Southern Idaho, Utah and western Colorado south to southern Mexico. Range does not overlap.
