Cicada expert Chris Simon splits her time between research on periodic cicadas in the United States, and on various cicada species in New Zealand. In part two of this cicada story, Alison Ballance is with Chris Simon in her Wellington garden, finding about the evolutionary history of cicadas in New Zealand, and about various aspects of their life cycle. Part one aired last week.
There are some great online cicada references: check out Chris Simon's Cicada Central, where you can see pictures and hear audio of cicada songs; Landcare Research has a virtual identification guide; and Te Ara also has lots of interesting information.
