Googling, this one says moth is like a humming bird. I probably have
seen them flitting about.

Yup , they're big moths . And that's what puzzles me , because I've never
seen one that size . We're bird watchers (well , kinda) and I'm pretty sure
that a moth the size of a hummingbird would attract our attention .
