Nymphs feed on fungi that develop in leaf litter. So far, this has been studied only in Florida on palm branch litter, but obviously this would also apply where cottonwoods produce so much litter. In Canada and the northern states, this genus is associated with willows, which are similarly trashy trees. --Andy Hamilton
