Thesis, Colorado State University, Fort Collins, CO 375 pages. 148 distribution maps. PDF Remarks: The type female for this species was collected at a light in Boulder, Colorado. Banks (1907a) wrote "One female from Colorado (Oslar) and two from Boulder, Colorado on August 9 (year not reported). Cockerell at light" (Weaver 1988). The only information available from the MCZC online collection is "Lectotype - female, Boulder, Colorado August 9 at light, T.D. A. Cockerell, No. 11692." No additional records for this species are known from the SPRB. Additionally, Herrmann et al. (1986) do not list records for L. stigma in Colorado or the basin.

Banks (1907a) reported "One female from Colorado (Oslar) and two from Boulder, Colorado on August 9 (year not reported), Cockerell at light." The Lectotype – female collected from Boulder, Colorado August 9 at light, by Cockerell is currently housed at MCZ (No. 11692). Herrmann and others (1986) did not list records of this species in Colorado indicating that the specimens were either damaged or unidentifiable (Ross, 1946); however, Weaver (1988) later decided the Colorado specimens were identifiable. No additional records for this species are known from the SPRB." The elevation they were found at was 5,400 feet and the adults were found in August. |
