What did I see? In my petunias yesterday morning was a small, maybe two-inch
long moth (at least what I think was a moth), flying like a hummingbird. It
was a very good flyer, with motions much like a dragonfly, and when it entered
a flower for a drink, its wings kept beating just like a hummingbird's. For
the most part, it was brown, with two distinct yellow bands around its body. I
live in Chicago.

What did I see?

Possibly a hummingbird clearwing moth. Definitely a moth in the Sphinx family
(Sphingidae).
