The Great Ash Sphinx
moth resides in much of the US with only a limited population
in the gulf states and in parts of Canada and Mexico. The caterpillars dine on Ash and Birch trees,
Lilac and Privet. The adults prefer deep throated flowers such as
evening primrose and Japanese honeysuckle. This Sphinx moth was
stuck to a Mexican Evening Primrose flower. Its tongue or proboscis
was wrapped around the pistil of the flower and the moth could not figure
out how to let go. After dissecting the flower we were able to free
the moth. These Sphinx moths are some of our largest with wingspans
of 3-5 inches.
