A Tiny Hummer?
Did you see what appeared to be a tiny hummingbird at one of your flowers?
Did it appear to be smaller than any hummingbird you've ever seen?
The explanation for such sightings is that what you have seen is a hummingbird moth (family Sphingidae). Below are two species often encountered in the U.S.

There are many species of these moths around the world, and they are commonly mistaken for hummingbirds. The reasons for this misperception are several: they are active in the daylight hours (most moths are not); they hover in front of flowers to feed; the probe the flowers for their nectar (although using a proboscis, not a beak); and they favor some of the same nectar-rich blossoms that are liked by hummingbirds.
The smallest hummingbird species in the world is the Cuban Bee Hummingbird, Mellisuga helenae, and it measures 5-6 cm in length (2.0-2.4 inches) and weighs a mere 1.6-1.9 grams (roughly 1/14 of an ounce). Most species, however, are larger: in the U.S., most species are 3.0 - 3.5 inches in length. Hummingbird moths are considerably smaller than the smallest hummingbird.
This recognition problem is perhaps the single most common query presented to the Hummingbird Society, often with a photo attached. Some are not convinced, despite the scientific evidence. When in doubt, one can always get closer and count the legs...it is a sure way to distinguish between an insect and a bird!
