We have quite a few H. thysbe this year for some reason. No complaints. They are pretty cool to watch. I think the tomato horn worm is Manduca quinquemaculata though, which is quite a bit bigger and does not have clear spots. Can be mistaken for hummingbirds at a distance. I have done this😊

Thanks for the rundown Josh. I am a little rusty on my sphinx moths. I was unaware of the feeding preference but it makes sense. With good rain (finally) our L. sempervirens is going to town and I see the adults on it all the time.
The two species of Hemaris sp. clearwing moths mentioned both feed on plants of the honeysuckle family as caterpillars. I’ve seen Snowberry Clearwing hornworms on Japanese Honeysuckle but they strongly prefer the native Coral (Lonicera sempervirens). BugGuide (a citizen science website for terrestrial arthropods) also mentions hawthorn, snowberry, and viburnum as larval hosts for the Hummingbird Clearwing, and snowberry, dogbane, and the native bush-honeysuckle Diervilla for the Snowberry. Massachusetts also has a third species, the Slender Clearwing (H. gracilis), which closely resembles the Snowberry, but whose hornworms feed on various species of blueberry and laurel.
