A luna moth

 I thought it was a tulip tree blossom knocked down by the winds. It was a luna moth, Actias luna. It was the shade of green that reminded me of tulip tree blossoms.

The guidebooks say luna moths frequently have a 4.5-inch wingspan, but this one was closer to 6.

The moth’s long tails have puzzled biologists. They spin and flap behind the moth’s body, kind of like a wobbly propeller. Scientists figured out that the tails are acoustic deflectors.

Bats hunt by echolocation. They emit sounds that bounce off prospective targets, allowing the bats to find their prey.

If the bat is using radar, the moth is using stealth technology.
