Abstract:
Drones, attracted to an observation site by a scented lure, left the lure to fly directly towards a small object suspended nearby. An object the size of a queen bee was detected at distances up to 2 m. It is estimated that at this maximum distance the object will have decreased the light incident on a single rhabdom by 6%.
