Cosmia praeacuta

Cosmia praeacuta

Attracted to lights. Cosmia praeacuta or Acytonix epipaschia??

C. praeacuta
This and your 2 other praeacuta images moved from Cosmia to new species page.

An interesting comment by Jan, saying that "Cosmia epipaschia so far is known from the holotype only." The holotype (a single specimen, shown as figure # 2 on this plate) was collected in New Mexico and described by Grote in 1883. Assuming that Jan's statement is true, all other records and specimens of the species "epipaschia" since 1883 have been misidentifications.

Moved from Moths.

Cosmia praeacuta
Cosmia praeacuta. In C. praeacuta orbicular and reniform spots have very distinct black outline, while in Cosmia epipaschia these spots are indistinct. See the reference below for identification of North American species of Cosmia:

Lafontaine, J. D. & Troubridge, J. T. 2003. Review of the genus Cosmia (Lepidoptera: Noctuidae) in North America, with description of a new species. The Canadian Entomologist, 135: 325-336

According this reference Achytonix epipaschia also belongs to the genus Cosmia. Cosmia praeacuta has several forms and sometime is identified as C. epipaschia. Hovewer, Cosmia epipaschia so far is known from the holotype only.

Thanks Jan, I'll have to try to get the article. One or both seem to be fairly common here.
