moth, who are they
These were in the garden in July. I have not seen a pair before. They stayed on this shrub from morning to and threw the night. The next morning all that we found were there wings. We placed the wings in clear document holder. Because of the different size of half moon shapes on the wings, it was assumed that we had one male and one female.

Your moths are Cecropia Moth, Hyalophora cecropia, the largest North American Giant Silkworm Moths. They may have been a mating pair. The adults live only long enough to mate and lay eggs and they cannot even eat as they don’t have working mouthparts. Sounds like a bird or other predator got a good meal.
