ECHOLOCATION OF NOCTUID MOTHS (LEPIDOPTERA, NOCTUIDAE)
In this study noctuid moths tethered to a thin wire were flying in total darkness among
several model obstacles with different coefficients of acoustic reflectance. It turned out
that the probability of collisions of a flying moth with the obstacles depended on the
obstacle reflecting power in the ultrasonic range. Among those species who demonstrated a
reduction in number of collisions with the obstacles reflecting ultrasonic waves
effectively, Amphipyra perflua and Crino satura should be especially
noted. Such a correlation was only observed on the background of click emission by the
moths. The analysis of results permitted to suggest that species of noctuid moths studied
are capable of echolocating.
