Size: medium
Attracted to blacklights. Elevation 4319'. Specimen sent to Chuck Harp to confirm the ID.

Not S. incubus
I think that this and your photo #1481504 are more likely to be S. levis. I'm not clear if you mean that Chuck Harp has confirmed these or if the determinations are yours and you sent the specimens to him and may be still waiting for his confirmation.

Compare with Jim Vargo's pinned specimen at MPG here and DNA barcoded samples CNCLEP 00102299 and CNCLEP 00102299 at BOLD here. Also see your photo #1481513 which was identified by Jim Troubridge. When I increased the exposure by a half stop and slightly increased the color temperature of this image, it looked fairly identical to 1481513.

Troubridge (2008) (1) separates the two by range with incubus found in Washington State and eastern Oregon and levis east of the Rockies from southern Alberta to Colorado. If these are Chuck's determinations, you might want to ask him to examine the genitalia.

Moved from Sympistis.
