This bug with wings was competing with Great Northern Bumblebees, honeybees, bottle flies and other insects for nectar at the Provence Lavender bush/flower in my backyard. It is always swamped with insects in June and July and even in August and in all the years I have watched the insects gather at this bush I had never seen this one before today. It has almost transparent wings, something like a hummingbird moth or a hawk moth. And there is some green color on the shoulders.
