Dr.William H. Cade ('''Bill Cade''') is a biologist specializing in mating systems (especially of the Cricket (insect) ). His research areas include studying the evolution of mating behavior in crickets and the cricket/fly acoustical research, as well as studying the crickets and grasshoppers of Africa. Cade is the president of the University Of Lethbridge . For a picture and more information at the President's page here http://www.uleth.ca/prs/about.html EDUCATION Cade completed his undergraduate and graduate degrees at the University Of Texas At Austin , where he was a member of the Kappa Sigma fraternity. RESEARCH In 1974, Cade discovered that the parasitic fly ''Ormia ochracea'' is also attracted to the song of the male and uses it to locate the male in order to deposit her young on him. It was the first example of a natural enemy that locates its host or prey using the mating signal. Cade discovered a link between crickets and a parasitic fly. The mating call of the male field cricket (''Gryllus texensis'') is used by ''Ormia ochracea'' in locating the cricket. This small yellow fly is found throughout the southern United States and as far north as Hamilton, Ontario. The flies are predators looking for a host. Since then many other species of crickets have been found to parasitized by the same fly around the world. The Texas Field cricket: Gryllus texensis http://buzz.ifas.ufl.edu/479a.htm Most recently, in the fall of 2006, research by Marlene Zuk has revealed the relationship between the cricket and the fly as one of the fastest examples of evolution ever recorded. Pressure from the ''Ormia ochracea'' has caused the crickets to evolve a silent male which has wings that look like female wings. In addition to his this work, Cade has a long collaboration with Dan Otte for many years collecting and studying the crickets and grasshoppers of Africa. EXTERNAL LINKS
