Katydids (Orthoptera: Tettigoniidae) are members of the grasshopper order, and like most of their relatives they feed on plants. They eat not only leaves and stems but flower petals and pollen as well. Today I came across a young nymph that was eating the petals and pollen of a sulphur cinquefoil (Potentilla recta, Rosaceae).
Although native to Eurasia, sulphur cinquefoil was introduced to North America long ago and has since spread to most of the continent. It’s particularly common in disturbed areas along roads, fields, and weedy spots. These sunny locations filled with herbaceous plants are also ideal habitats for katydids, making sulphur cinquefoil a common and readily available food plant.
