Enchenopa binotata is a complex of six treehopper species that have diverged along host plant lines. When females were forced to oviposit on ``adopted'' host plants, few eggs were deposited. Fewer eggs hatched on ``adopted'' hosts and those that did hatch did so in response to the phenology of the ``adopted'' host. Mortality of nymphs on ``adopted'' hosts was substantially higher than on native hosts. These and other data support a sympatric model of speciation through shifts in host plants.
