Genus Scudderia in North America north of Mexico
Identification of species
Males of most species in this genus can be identified on the basis of their distinctive dorsal process, a rearward dorsal extension of the last abdominal segment.
Females are difficult to identify, but the ovipositors differ enough among the species to be of some help.
Scudderia eggs are extraordinarily thin and flat --as befits the fact that the female inserts them between the upper and lower epidermal layers of leaves! The female's oviposition technique is easily observed. Deprive a fertilized female of suitable oviposition sites for a day or so and then transfer her to the leaves of most any plant. She will usually begin to lay in a few minutes.
Narrow-beaked katydids (Turpilia rostrata) also lay their eggs in the edges of leaves.
