Carolina Sphinx Moth
I have the summer evening flowering moon flower at several locations in my landscape. One moth that really likes moon flower is the Carolina Sphinx Moth (Manduca sexta). The large all-green caterpillar is known as the tobacco hornworm.
I observed the moth at the threshold of my garage door last evening, and which is located next to a patch of night blooming moon flower.
This is a large moth with large fore-wings and orange-yellow spots along the abdomen. They are strong flyers and have rapid wing beats.
Adults are nectar feeders and fly at dusk.
This species is native to the United States, and this maps shows the location of where the tobacco sphinx moth occurs, with Maryland looking like a hot spot.
