Phaneropterine Katydids

Eastern Cypress Katydid (Inscudderia walkeri) male.

Microcentrum louisianum male specimen. The stridulatory area at the base of the left forewing of this specimen was cut out and glued to the side of forewing by its dorsal surface. This exposes the file teeth for examination.

Microcentrum louisianum, male specimen dorsal pronotum. The many pigmented setal pits (small brown dots) distributed over the entire pronotal disk distinguish this species from the closely related and sympatric M. retinerve. M. retinerve has few such pits and they mostly occur along the pronotal carinae.

Microcentrum retinerve, female (one of four individuals reared from eggs by Susan Wineriter).

Microcentrum retinerve, female pronotum. The squarely truncate front pronotal margin serves to distinguish this species from M. rhombifolium.

Microcentrum retinerve, male. The brown on the stridulatory area distinguishes the males of this species from those of M. rhombifolium.

Microcentrum rhombifolium, female specimen pronotum. The tooth on the front pronotal margin serves to distinguish this species from Microcentrum retinerve. The degree of development of the tooth is variable but it is always evident (in both sexes).

Modest Katydid (Montezumina modesta) male.

Mediterranean Katydid (Phaneroptera nana) male.

Scudderia cuneata, dorsal view of male dorsal process. Fig. 3 (Plate IX) in Rehn, J.A.G. and M. Hebard. 1914. Studies in American Tettigoniidae: 1. A synopsis of the species of the genus Scudderia. Trans. Am. Entomol. Soc. 40: 271-314.

Scudderia furcata, female. The globule and other material beneath the ovipositor are the remains of a spermatophore and the spermatophylax that accompanied it.

Scudderia furcata adult. This image is one of a series illustrating the development of this katydid on Singing Insects of North America(http://entnemdept.ufl.edu/walker/buzz/063dev.htm), where T.J. Walker (2006) writes: The photographs below document the development of a nymph sent me in early July by John Spooner, University of South Carolina at Aiken. John had obtained the eggs the previous fall from a female from Rapides Parish, Louisiana, sent to him by Steve Shively, Wildlife Biologist, Kisatchie National Forest. John noted that the eggs had been laid in leaves that died back in the winter and that he had placed them on wet filter paper on May 20. The earliest hatch was June 23. John surmised that "eggs can be laid in deciduous leaves which drop to the substrate in the fall/winter, absorb water from spring rains and hatch. The nymph was reared in a container that John supplied, on lettuce supplemented by bits of dry cereal and catfood. It traveled with me on a month-long camping/collecting trip from Florida to California and back."

Scudderia furcata, pink female.

Scudderia furcata, pink/dark female. This individual shows the inadequacy of a color classification system that uses only green, pink, and dark. This female is both slightly pink and slightly dark (but not at all green).

Scudderia furcata late reared 1st instar.
