The sound comes from a white membrane on the male's midsection that is made to vibrate, Schmidt and Rydzewski said. The area beneath it acts like an echo chamber. “It’s a lot of the same sort ...
As the adult cicadas emerge in the daytime, large numbers are consumed by birds. [36] Thopha cicadas have also been found in the stomachs of foxes. [37] The double drummer is one of the large cicada species preyed on by the cicada killer wasp (Exeirus lateritius), [36] which stings and paralyses cicadas high in the trees. Their victims drop to ...
"The sound is cicadas," the post said. "Cicadas are a super family of insects that appear each spring. The nymphs have lived underground for 13-17 years and now this time they are hatching."
Some cicadas produce sounds louder than 106 dB (SPL), among the loudest of all insect-produced sounds. [2] They modulate their noise by positioning their abdomens toward or away from the substrate. The sound of an Amphipsalta zelandica cicada in Lower Hutt , New Zealand , recorded in mid-February, 2006
