On our morning walk, we happened to see a Hummingbird Clearwing taking nectar from a Swamp Milkweed near the pond. While we have seen the Snowberry Clearwing (Hemaris diffinis) several times this year, this is the first Hummingbird Clearwing (Hemaris thysbe) sighting of the year. I thought this might be a good opportunity to illustrate how to differentiate the two species.
