I can't find any hummingbird moth pictures right at the moment, but I've had considerable fun trying to grab them just right. They're a little easier to get in the air than bees, because they hover over the flowers, as butterflies do, while bees tend to land.
As spring approaches, I hope to continue my neverending quest to get a good dragonfly in flight. The number of rejections here is nearly 100 percent and I have yet to get a really good one. I got close last year.
