Everyone's looking for a warm spot on a cold day.
You can often find insects in weather one might think is too cool for their liking. Often it's a sunny day, and the sun's radiance warms them enough to be active despite the cool temperature. Some require a lot of heat energy because they move their body parts so rapidly, like dragonflies who have very rapid wing beats.
So, it was surprising to find this Hummingbird Clearwing (Hemaris thysbe) out today. Hummingbird Clearwings are day-flying moths that feed on long or deep-throated flowers. Their wingbeats are a rapid blur, and their manner of flying can make them easy to mistake for a hummingbird, hence the name.
The other surprise was seeing it land. They are busy pollinators, moving from flower to flower. I had never seen one stand still before.
