Observation notes: Time: 11:36 a.m. Sky: Cloudy. Habitat: Backyard filled with lawn grass, near a small area of gravel. Notes: I found this enormous sphinx moth laying motionless in my backyard grass, wings fully extended. I thought it was dead at first, but it turned out to be fully alive. I tried releasing it around dusk that evening, but it became apparent that it couldn't fly properly, as it was unable to lift itself more than a couple inches off the ground, probably due to the large chunk missing from one of its hindwings. Despite its worn condition, I decided to mount it so that it didn't go to waste. After looking through the Larimer County sphinx moth checklist, I'm fairly certain that it's a Five-spotted hawkmoth, not a Carolina sphinx.
