A big brown bat (Eptesicus fuscus)
approaches a wax moth (Galleria mellonella),

The big brown bat is poised to scoop
the wax moth into its tail membrane. The bat will
then dip its head in to eat its prey. Photo 4
The researchers use an infrared camera
to capture high-speed (250 frames per second), detailed
