I became interested in insects, and cicadas in particular, as a small child growing up in New Plymouth, New Zealand. There the cicadas are common and noisy and easy to play with, and I learnt to tell all the species around me by their songs. I studied for a BSc in entomology at Lincoln University, Lincoln, Canterbury, New Zealand, and during my final year was fortunate to meet my current employer, Dr Chris Simon (Professor, Ecology and Evolutionary Biology, University of Connecticut, USA), who had been studying cicadas in New Zealand, Australia and North America for many years. I did an MSc studying the phylogeography of a New Zealand cicada, Maoricicada campbelli, at Victoria University of Wellington, Wellington, New Zealand under Chris Simon and Dr Geoffrey K. Chambers (School of Biological Sciences, Victoria University of Wellington). Since then I have been working at the Ecology and Evolutionary Biology department of the University of Connecticut, in the lab of Chris Simon, where I am studying phylogenetic and phylogeographic relationships of worldwide groups of cicadas. I work in a molecular lab sequencing specimens, in the field collecting, recording and observing, and under a microscope identifying and describing new species.

 

I am particularly interested in three aspects of cicada biology - their evolutionary relationships, their communication systems and describing new species. Cicadas are found worldwide in temperate to tropical ecozones, and are well-known insects. However their higher taxonomy is often poorly understood, and our new molecular work is leading to new understandings of many tribal boundaries. An NSF grant to Dr Chris Simon, of which I am a collaborator, has just been awarded to study the molecular relationships of the family Cicadidae, extending the scope of previous grants that I have collaborated on studying New Zealand cicadas and the worldwide tribe Cicadettini.


I am very interested in cicada communication. Together with my husband David Marshall (Postdoctoral researcher, Ecology and Evolutionary Biology, University of Connecticut), we have recorded the sounds of hundreds of species of cicadas including species from Australia, New Zealand, the United States, China, South Africa, Fiji, Argentina and the Philippines. We are very fortunate in that the opportunity to collect cicadas in many countries has given us a worldwide perspective on cicada songs and communication. Our understanding of the duetting pair-formation system in some cicadas led to the discovery of the first acoustic aggressive mimic ever found - a large predaceous katydid in Australia (Chlorobalius leucoviridis) that clicks back to male cicadas in order to attract them and eat them. I have also worked on aspects of the communication system of the unique Periodical Cicadas (Magicicada spp.) of North America, along with collaborators David Marshall and John Cooley (Ohio State University), who discovered the 7th species of this complex and worked out much about their singing and courtship behaviour.

 

There are many undescribed species of cicadas worldwide. In Australia especially, there remain hundreds of species currently unknown to science, sometimes morphologically cryptic but with unique songs. Along with collaborators such as Dr. Max Moulds (Australian Museum, retired), Dr Allen Sanborn (Department of Biology, Barry University, Florida), Dr Young June Lee (Ecology and Evolutionary Biology, University of Connecticut) and David Marshall, I am interested in describing some of these species, including publishing their songs.

 


 Systematics

In collaboration with Chris Simon, David Marshall and others, I am currently obtaining molecular data for projects on the phylogeny of Cicadidae, the genera Kobonga, Gudanga and Tibicen, and the Tribe Cicadettini.

Cicada songs and communication

Together with David Marshall and John Cooley, we are working on papers discussing cicada communication, especially aspects of the duetting pair-formation system found in some taxa.

Species descriptions

In collaboration with David Marshall, Max Moulds and others, we are working on descriptions of new species of cicadas from New Zealand, Australia and North America, several discovered through recognition of their unique songs.
