The first time I saw a Snowberry Clearwing Moth in the garden I wasn't entirely sure what it was. It had several hummingbird characteristics, it was fast moving (they can reach speeds of 35 mph), it had fast beating wings that hummed, and, it hovered over blossoms while it sipped nectar, but, its coloring, antennae, six legs and long, butterfly-like proboscis clearly said "this is an insect in the butterfly/moth family"! It didn't take long to identify it as
Hemaris diffinis, a day-flying moth in the sphinx family.

The Snowberry Clearwing Moth is a mid to late summer visitor to my garden. They're really quite interesting looking moths and have the same yellow and black coloration as bumblebees. They have large eyes and a long tongue/proboscis perfectly adapted for reaching deep down in tubular flowers like
summer phloxes,
verbena and
monarda for hidden nectar. They're good pollinators and like bees, pollen sticks to their hairy bodies and is transferred to other flowers as they move about the plant community.
Now, that I've just typed that paragraph, I'm not sure why I thought it was a hummer when it clearly resembles a bumblebee!
Hemaris diffinis's bee mimicry worked on me and it probably does a pretty good job insuring it isn't an easy meal for a fast moving bird! Oh isn't nature amazing and oh so clever!

Now that summer is sort of winding down here in the Mid-South, I've been checking the Arrowwood viburnums, Southern bush honeysuckles and the Loniceras (host plants) for any of its emerald green eggs. So far I haven't found any, but, I'll continue to keep a look out for them and any green hornworms as they search for the right spot in the leaf litter to pupate and wait the winter out. Maybe, I'll get lucky and see the moth emerge in the Spring!

Until then, I'll enjoy them on warm summer days as they hover and dart about the garden.
