Lost this ID on my previous account. rayray hoping that you see this, you identified this moth before as being part of an isolated population in CO mountains! Found that really incredible and would love to confirm this ID again. Previous ID: Neoarctia brucei - app will not find it as a suggestion

Hyalophora cecropia ("H. gloveri Blend Zone" ?)

H. cecropia ("cecropia x gloveri blend zone" ??)
Coll. at lights

Moths from this area are often highly variable, some look like cecropia, some like gloveri, and others exhibit a range of intermediate traits. This moth is a bit unusual for typical cecropia and suspected of being a backcross (per. comm. & per. observ.)

Picture number 2 compares the "Denver cecropia" (left) with a H. gloveri (right) from Conifer, a few miles west of Denver.

This specimen of Colorado "cecropia moth" exhibits traits seen in both H. cecropia & gloveri and is very likely a HYBRID or backcross between the two. The distinctive red postmedial scaling is a trait typical and diagnostic of cecropia (not so for gloveri). Given locality, it would not be unlikely to encounter Hyalophora specimens with "cecropia/gloveri" influence - esp. since both taxa are known to occur in this area.

Hyalophora cecropia populations occupy suitable habitats across parts of eastern Colorado and extend to the Rockies where they are typically replaced by H. gloveri at higher elevations.

In the Denver area, H. cecropia has been collected on a number of occasions; however, whether cecropia moths are native locally or have been introduced into the Denver metro area is still in question.
