The European free-tailed bat, Tadarida teniotis, forages in uncluttered airspace by using intense narrow-band echolocation calls with low frequency (11-12 kHz), and feeds on relatively large flying insects, mainly (90% by volume) of the tympanate orders Lepidoptera and Neuroptera. The use of low-frequency echolocation calls without strong harmonics appears… CONTINUE READING
