We really enjoy your website. Fun & interesting letters. We have a mysterious bug sighting to report. Near dusk, we spotted what looked like a small hummingbird going from flower to flower on our porch. We looked closely at him, and he was fearless. Totally oblivious to us, less than a foot away from him. He had kind of a fuzzy dark yellow body, and wings moving so fast you coudn’t see them. His tail was black or dark brown, and was actually similar in shape to that of a crawdad! He had six legs (or so), so we know he wasn’t a bird. He was about 2 1/2 inches long. Is this a moth of some sort? He didn’t seem to be attracted to the porchlight, just the flowers. We’re in central Indiana, and we spotted him on a warm & humid evening in early July.
Thank You — J & C & D
