A periodical cicada ascends to
A periodical cicada ascends to the treetop to join his brood-mates. Males create sound by vibrating tymbal organs on both sides of their abdomen just beneath their wings. Hundreds of males form loud choruses to attract others of their own species. Watch as a pharaoh cicada cruises the chorus using his courtship song to locate an interested female. Nearby, another hopeful male gets the attention of a coy female who flicks her wings several times. Wing flicks accompanied by clicking sounds usually signify a willingness to mate. However, as the suitor closes in to seal the deal, his hopes are dashed when the lady changes her mind and flies away. On a nearby branch another male finds a mate and fulfills his biological imperative.
