Conocephalus Anisoptera maculatus

Behaviour: 

Males call both during the day and early at night; the call is a continuous, wide-spectrum buzz, with most of the acoustic energy within 20–50 kHz but without a distinct frequency peak; lower frequency portion of the call is easily audible to the human ear (Figs. 45A–C). [1]
