The floriphilic katydid, Phaneroptera brevis, is a frequent flower visitor of non-native, flowering forbs
Distribution of consumers in a patch of vegetation can be predicted by resource availability and explained by the resource-concentration and optimal-foraging hypotheses. These hypotheses have not been explored for flower-visiting Orthoptera because they are deemed less economically...
