Phasmid
Guides
Anisomorpha buprestoides
Southern Two-striped Walkingstick, Devil Rider, Musk Mare, Twostriped Walkingstick
Anisomorpha buprestoides is among the largest insects in the continental United States, with females reaching nearly 100 mm. This phasmid exhibits extreme sexual size dimorphism, with females substantially larger than males. The species is notable for its potent chemical defense spray containing anisomorphal and related compounds, which can cause severe eye irritation in humans. Three regionally distinct color morphs occur: brown, white, and orange forms, with the latter two restricted to specific areas of Florida.
Carausius morosus
Indian Walking Stick, Common Stick Insect, Laboratory Stick Insect
Carausius morosus is a parthenogenetic phasmid native to Tamil Nadu, India, widely distributed globally through accidental introductions and captive culture. Females reproduce without males; no wild males have been reported, though gynandromorphs occasionally occur in captivity. The species is nocturnal, feeding at night and remaining motionless during daylight hours. It has become established outside its native range in locations including Great Britain, Portugal, South Africa, and the United States, where it occasionally damages ornamental plants.
Diapheromera femorata
Northern Walkingstick, Common Walkingstick
Diapheromera femorata is the most widespread and economically significant stick insect native to the United States. Adults reach 75–95 mm in length, with females typically larger than males. The species is notable for periodic outbreak populations that can cause localized defoliation of trees, particularly oaks. It is the only phasmid of documented economic importance in North America, with historical outbreaks affecting thousands of hectares in Michigan, Wisconsin, Arkansas, and Oklahoma.
Diapheromeridae
Common Walking Stick Insects
Diapheromeridae is a family of stick insects within the order Phasmatodea. As of 2025, its exact position within Euphasmatodea remains unresolved (incertae sedis), not assigned to any known superfamily. The family contains two subfamilies: Diapheromerinae and Palophinae. Some species are notably large, with Paraphanocles keratosqueleton exceeding 30 cm in length. Members of this family are phytophagous and exhibit cryptic stick-like morphology typical of the order.
Haplopus scabricollis
Mayer's Walkingstick
Haplopus scabricollis is a Caribbean walkingstick known as Mayer's Walkingstick. It inhabits island and coastal environments in the Caribbean Sea and southern Florida, including the Florida Keys, Dry Tortugas, Cayman Islands, and Swan Islands. The species shows a restricted insular distribution pattern characteristic of many Caribbean phasmids.
Leptoglossus
leaf-footed bugs
Leptoglossus is a genus of true bugs in the leaf-footed bug family Coreidae, tribe Anisoscelini. Species are characterized by leaflike dilations of the hind tibia, a diagnostic trait of the genus. The genus is distributed throughout the Americas, with some introduced populations in Europe and Asia. Several species are economically significant agricultural pests, notably L. occidentalis, which has become invasive in multiple continents.

blatchley walkingstick, slender-bodied walkingstick
Manomera is a genus of walkingsticks in the family Diapheromeridae, established by Rehn and Hebard in 1907. The genus contains at least three described species found in North America: M. blatchleyi, M. brachypyga, and M. tenuescens. These insects are characterized by their elongated, stick-like bodies typical of phasmids. The genus is part of the diverse Diapheromeridae family, one of the largest families within the order Phasmida.
Megaphasma denticrus
Giant Walkingstick
Megaphasma denticrus, the giant walkingstick, is the longest insect species native to North America, with females reaching over 150 mm (6+ inches) in body length. This phasmid inhabits wooded areas across the south-central United States and parts of Mexico, where it feeds nocturnally on foliage of trees and shrubs. The species exhibits sexual dimorphism, with females substantially larger than males, and possesses distinctive rows of teeth on the underside of the middle femora that aid in identification. Both sexual and asexual reproduction have been documented, though the resulting ploidy of parthenogenetic offspring remains poorly understood.
Pseudosermyle strigata
Striped Walkingstick
Pseudosermyle strigata, commonly known as the striped walkingstick, is a species of phasmid in the family Diapheromeridae. It is native to North America, with documented occurrences in the southeastern United States. The species was described by Scudder in 1900. Like other walkingsticks, it exhibits cryptic morphology resembling plant material.
Timema chumash
Chumash Timema
Timema chumash is a species of walkingstick insect in the family Timematidae, endemic to California. Like other members of the genus Timema, it is a small, wingless phasmid with reduced body size compared to most stick insects. The species was described by Hebard in 1920. It is part of a genus notable for being the only known genus of stick insects in the Americas with a relictual distribution in western North America.
