Summary

Scudderia is a genus of bush katydids characterized by their herbivorous nature and preference for various habitats across North America. Identification relies heavily on the terminalia, especially in males. Most species demonstrate significant habitat and dietary preferences aligned with deciduous plant life.

Physical Characteristics

Range from 36-50 mm in length. Color pattern of living specimens can be variable but is rarely diagnostic.

Identification Tips

Identify species within this genus by examining the terminalia (parts at the end of the abdomen). Males require examination of these parts from both the side and above, focusing on the shapes of the supra-anal plate and the subgenital plate. Wing shape and coloration patterns may also assist in identification.

Habitat

Deciduous forests, shrublands, grasslands, and lush areas within deserts. Varying preferences among species, with many favoring foliage of broad-leaved woody deciduous plants and others favoring rank herbaceous growth.

Distribution

Much of North America, from southern Canada southward. Commonly found in southeastern US and across eastern North America.

Diet

Herbivorous; nymphs primarily feed on flowers, while adults prefer broad-leaved woody deciduous plants.

Life Cycle

Eggs are usually laid singly or in a row along the edge of a leaf, with at least the base inserted within the leaf. Eggs overwinter and hatch in spring. Generally, one generation per year.

Reproduction

Eggs laid along leaves, often overwintering before hatching in spring.

Ecosystem Role

Play a role in the herbaceous and woody plant communities as both herbivores and prey for various species.
