common true katydid, northern true katydid, rough-winged katydid
Pterophylla camellifolia is a large, nearly flightless katydid native to eastern North America. Males produce the iconic three-pulsed "ka-ty-did" call that gave katydids their common name. The species inhabits the canopy of deciduous trees and moves primarily by walking, running, or hopping rather than flying. Populations exhibit geographic variation in song structure, with northern populations producing two- to four-pulsed songs, southeastern populations faster multi-pulsed choruses, southwestern populations one- to two-pulsed songs, and a distinctive 8-15 pulse song restricted to central Iowa. Three subspecies are recognized based on morphological and geographic differences.
Pyrgocorypha
coneheads
Pyrgocorypha is a genus of conehead katydids in the family Tettigoniidae, established by Carl Stål in 1873. The genus comprises approximately 16 described species distributed across the Americas and southern and eastern Asia. Members of this genus are recognized by their distinctive head morphology, particularly the modified fastigium (cone) that projects forward from the vertex. The hook-faced conehead (Pyrgocorypha uncinata) is among the most distinctive North American species, characterized by a pronounced hook at the tip of its cone.
Pyrgocorypha uncinata
Hook-faced Conehead
Pyrgocorypha uncinata, commonly known as the hook-faced conehead, is a katydid species in the family Tettigoniidae. It is distinguished by its distinctive hook-shaped cone (fastigium), which curves downward at the tip and gives the species its common name. The species occurs in the southeastern United States, with records extending to northern Arkansas at the western edge of its range. Like other conehead katydids, it produces sound by stridulation and is active during the warmer months.
Scudderia
Scudder's Bush Katydids, bush katydids
Scudderia is a genus of bush katydids in the subfamily Phaneropterinae, established by Stål in 1873. Species in this genus are medium-sized insects, 30–40 mm in length, with a transcontinental distribution across North America. They are herbivorous, feeding on flowers as nymphs and woody deciduous plants as adults. Several species are economically significant as pests in citrus orchards and stone fruit production, particularly Scudderia furcata, the fork-tailed bush katydid. Males produce species-specific calling songs using file-and-scraper structures on their forewings, and species identification typically requires examination of the male supra-anal plate morphology.
Scudderia fasciata
treetop bush katydid, black-striped katydid
Scudderia fasciata is a species of bush katydid in the family Tettigoniidae, commonly known as the treetop bush katydid or black-striped katydid. It is native to North America, with documented records from the northeastern and north-central United States. Like other members of the genus Scudderia, it is an arboreal insect associated with trees and shrubs. The species was described by Beutenmüller in 1894 and is classified within the subfamily Phaneropterinae.
Scudderia mexicana
Mexican bush katydid
Scudderia mexicana, the Mexican bush katydid, is a phaneropterine katydid in the family Tettigoniidae. Adults measure 30–38 mm in length and possess slender wings. Nymphs are distinguished by a horn located between the antennae. The species has been documented feeding on leaves, including those of big-leaf mahogany (Swietenia macrophylla).
Scudderia pistillata
Broad-winged Bush Katydid
Scudderia pistillata is a species of bush katydid in the family Tettigoniidae, commonly known as the broad-winged bush katydid. It is native to North America and is one of eight recognized species in the genus Scudderia found in the United States and southern Canada. Like other bush katydids, it is primarily nocturnal and well-camouflaged in vegetation.
Scudderia septentrionalis
Northern Bush Katydid
Scudderia septentrionalis, the northern bush katydid, is a phaneropterine katydid in the family Tettigoniidae. It is found in North America. Like other Scudderia species, it is a bush-dwelling katydid with males that produce species-specific songs to attract mates. The species can be difficult to distinguish from congeners without examination of male genitalic structures.
Scudderia texensis
Texas bush katydid
Scudderia texensis, the Texas bush katydid, is a medium-sized katydid species in the family Tettigoniidae. Adults range from 40–56 mm in length, with geographic variation in size correlated with generation number and growing season length. The species exhibits bivoltine (two-generation) reproduction in the southern portion of its range and univoltine (single-generation) reproduction in the north. It is the most abundant Scudderia species throughout most of its range.
Steiroxys strepens
Noisy Shield-backed Katydid, noisy shieldback, shield-backed katydid
Steiroxys strepens is a shield-backed katydid in the family Tettigoniidae, first described by Fulton in 1930. It is known from limited observations in North America, particularly Oregon. The species belongs to a genus characterized by a distinctive dorsal shield-like structure formed by the pronotum extending over the abdomen.
Stilpnochlora
Neotropical Giant Katydids
Stilpnochlora is a genus of phaneropterine katydids in the family Tettigoniidae, native to tropical and subtropical parts of the Americas. The genus contains approximately 15 described species. Members are relatively large, leaf-like katydids, mostly green in coloration, with body lengths ranging from 5 to 10 cm depending on species. Females generally exceed males in size within the same species. Stilpnochlora couloniana is the largest katydid in the United States.
Tessellana
Tessellana is a genus of bush crickets (katydids) established by Zeuner in 1941. It belongs to the tribe Platycleidini within the subfamily Tettigoniinae. The genus contains six recognized species distributed across mainland Europe, the Middle East, and North Africa. The type species is Tessellana tessellata (Charpentier, 1825), originally described as Locusta tessellata.
Tettigoniidae
katydids, bush crickets, long-horned grasshoppers
Tettigoniidae is a large family of orthopteran insects containing over 8,000 described species, commonly known as katydids in North America and bush crickets in the United Kingdom. The family is the only extant member of the superfamily Tettigonioidea within the suborder Ensifera. Members are characterized by extremely long, thread-like antennae that often exceed body length, distinguishing them from true grasshoppers. The family exhibits remarkable diversity in size, ranging from 5 mm to 130 mm, and occupies varied habitats from tropical rainforests to temperate grasslands across all continents except Antarctica.
