One of those moths is this guy, who (in flight, not so much in still images) looks and sounds like a miniature hummingbird: https://en.wikipedia.org/wiki/Hummingbird_hawk-moth

I noticed these for the first time earlier this summer. Incredible insects! They really do give a hummingbird impression.

For many people, it is the other way around. It is very remarkable that there is a bird, which looks so much like a big version of this butterfly!

After all, in Europe these butterflies are commonplace, but I've never seen the American bird in my life.

rare instance where the German name Taubenschwänzchen ('little dove-tail') is nicer than the English name

Finding hawk moth caterpillars on my tomato plant was one of the bigger wtfs of my adult life

Very common around my mom's house.
