Parasitoids that locate their hosts by eavesdropping on the acoustic signals of other insects can be collected in traps baited with audio signals that mimic the sounds of the parasitoid's hosts. I describe a new acoustic trap designed to capture Emblemasoma erro Aldrich (Diptera: Sarcophagidae), an eavesdropping parasitoid of cicadas whose phonotactic behavior differs from that of the acoustic parasitoids targeted by previous trap designs. Specifically, unlike some other acoustic parasitoids, E. erro often remains at an artificial sound source only a few seconds, so the new trap features multiple, oblique side entrance funnels with large outer apertures that allow E. erro to rapidly access the trap's interior. The trap also has a modular design that allows the broadcast loudspeaker to be used independently of the trapping apparatus, and the trap is lightweight and easily transported in the field.
