Polistes dominula
European Paper Wasp
Polistes dominula is a highly successful invasive social wasp native to Eurasia that has established populations across North America, South America, New Zealand, South Africa, and other regions. First detected in North America near Boston in 1978, it has become one of the most abundant wasps on the continent. The species builds small, exposed paper nests in protected locations and preys primarily on live insects, particularly caterpillars. Unlike yellowjackets, it does not scavenge for meat or sugar. Its rapid spread has been attributed to ecological flexibility, superior competitive ability, and tolerance of human-altered environments.

Tanaoceridae is a small family of grasshoppers comprising two genera, Mohavacris and Tanaocerus. These insects are notable for their exceptionally long, thread-like antennae that equal or exceed body length, a trait unusual among Caelifera that can cause confusion with crickets (Ensifera). They are nocturnal, winter-active insects of arid regions, with apterous (wingless) bodies and cryptic coloration adapted to desert environments.

Tanaocerus
desert long-horned grasshoppers
Tanaocerus is a genus of desert-dwelling grasshoppers in the family Tanaoceridae, containing at least two described species: T. koebelei and T. rugosus. These insects are restricted to arid regions of the southwestern United States and northwestern Mexico. The genus is notable for its elongated antennae, a distinctive trait that separates it from most other grasshopper groups.

Tomonotus mexicanus
Mexican Oak-leaf Grasshopper
Tomonotus mexicanus is a grasshopper species in the family Acrididae, described by Saussure in 1861. It belongs to the tribe Arphiini within the subfamily Oedipodinae, commonly known as banded-winged grasshoppers. The species is endemic to Mexico, with records from central and northeastern regions. It is known in English as the Mexican Oak-leaf Grasshopper, though the origin of this common name is not documented in available sources.

Trachitropis arizonicus
Trachitropis arizonicus is a species of grasshopper in the family Pamphagidae, a group commonly known as the toad grasshoppers. The genus Trachitropis is native to arid and semi-arid regions of western North America. Species in this genus are characterized by their robust, toad-like body form and are typically associated with rocky or gravelly desert habitats. The specific epithet "arizonicus" indicates its primary association with Arizona.

Trachyrhachys
Trachyrhachys is a genus of band-winged grasshoppers in the family Acrididae, established by Scudder in 1876. The genus contains at least four described species distributed across western North America, including the finned grasshopper (T. aspera) and Kiowa grasshopper (T. kiowa). These grasshoppers are classified within the subfamily Oedipodinae and tribe Psinidiini.

Trachyrhachys aspera
Finned Grasshopper
Trachyrhachys aspera, commonly known as the finned grasshopper, is a medium-sized band-winged grasshopper native to the shortgrass prairie ecosystems of western North America. This species exhibits strong habitat fidelity to blue grama grass (Bouteloua gracilis) dominated grasslands, where it functions as a subdominant member of grasshopper assemblages. The species is notable for its late-season phenology, hatching approximately four weeks after the sympatric Trachyrhachys kiowa, and for its highly specialized diet consisting almost exclusively of blue grama grass. Despite its potential economic impact as a forage competitor with livestock, populations have remained chronically low with no documented outbreak events.

Trachyrhachys coronata
crowned grasshopper
Trachyrhachys coronata, commonly known as the crowned grasshopper, is a band-winged grasshopper in the family Acrididae. It is one of approximately 12 species in North America that overwinter as nymphs rather than eggs, with adults present early in spring. The species is found in western North America, particularly in Colorado and New Mexico. It belongs to the subfamily Oedipodinae, which is characterized by banded wings and often inhabits open, dry habitats.

Trachyrhachys kiowa is a medium-sized band-winged grasshopper inhabiting shortgrass and mixedgrass prairies of western North America. It feeds almost exclusively on grasses and sedges, particularly blue grama, and can become an economically damaging component of outbreak populations. The species is known for its dispersive behavior and intermediate hatching phenology, emerging two to three weeks after early-hatching species like the bigheaded grasshopper.

Trichochrous insignis
Trichochrous insignis is a species of jumping stick (family Proscopiidae), an exclusively Neotropical group of grasshoppers characterized by their stick-like appearance and elongated morphology. The species was described by Hebard in 1931 from Formosa Province, Argentina. Members of this family are commonly known in Spanish as 'bicho palito' (stick bug) and are distinguished from true walkingsticks (order Phasmida) by their jumping ability and grasshopper affinities. The taxonomy of Proscopiidae remains incomplete, with many species potentially undescribed.

Trimerotropini
band-winged grasshoppers
Trimerotropini is a tribe of band-winged grasshoppers in the family Acrididae, subfamily Oedipodinae. The tribe comprises at least 70 described species distributed across five genera: Circotettix, Conozoa, Dissosteira, Spharagemon, and Trimerotropis. The genus Trimerotropis alone contains 49 recognized species and has been described as an ecologically important group of American grasshoppers. Members of this tribe serve as hosts for parasitoid flesh flies in the family Sarcophagidae.
