Nancy Collins fell in love with tree crickets when a male two-spotted tree cricket found his way onto one of the potted plants on her apartment balcony and began to sing. That encounter led to one of the more remarkable stories in present-day singing insects research. Nancy’s passion has led to a comprehensive web site on tree crickets, expeditions in North and Central America, and co-authorship of scientific papers describing new species.
Nancy now lives in rural Racine County, Wisconsin, and last week showed me the study plot she is managing for her experimental studies. Her projects include the distribution of tree cricket species in Wisconsin, identifying characteristics of the various species’ nymphal stages, and color variation among Forbes’s tree crickets. That last species ranges considerably, from largely black to quite pale, often in the same local population. Nancy is enclosing groups of tree crickets segregated by color on various host plants, and will follow their offspring next year to begin sorting out genetic and other influences on that color variation.
During that visit I was able to add a few singing insect species to my spreadsheet for Racine County.
Note: the name in the title is Nancy’s, not mine. It is her handle for Internet use, combining the family name for the tree crickets (Oecanthinae) with her own. She does not capitalize the Nancy portion, however.
