The mole cricket family, Gryllotalpidae, is currently represented in the continental United States by two native and three introduced species. The native species, Gryllotalpa major Saussure and Neocurtilla hexadactyla Perty, produce sexual advertisement calls of chirps, while the introduced species, Scapteriscus borelli Giglio-Tos and S. vicinus Scudder, produce calls of trills like most other species in the family. Scapteriscus abbreviatus Scudder does not have an advertisement call. We used a scanning electron microscope to photograph forewings and describe the male and female condition of Gryllotalpa major for the first time. In addition we compared forewings of males of the four calling species to determine whether or not call type was linked to morphology of the stridulatory apparatus. The female G. major forewing was compared with those of females of the other calling species, including S. vicinus, which has previously been reported to produce low-amplitude sounds. Although there are generic differences in morphology of the stridulatory apparatus of value to taxonomists, there are no clear differences that can be used to segregate the mole cricket males into chirping and trilling species. The female G. major wing has a more highly developed stridulatory file than females of the other species from the continental United States.
