This video from Denmark says about itself:
This is the sound of the moth “Acherontia atropos”.
The sound is rare in the world of moths, and it is the only moth in Denmark which makes a sound.
It was instantly recognizable by the terrifying markings on the thorax, the death’s-head hawkmoth on the beach at De Koog. It was sitting literally on beach post #19.
