Hippobosca longipennis
dog fly, louse fly, blind fly
Hippobosca longipennis is an obligate blood-feeding ectoparasitic fly in the family Hippoboscidae. It primarily infests wild and domestic carnivores, particularly canids and hyaenids, but has been recorded on felids and occasionally humans. The species is larviparous, with females producing 10–15 larvae during a lifetime of four to five months. It serves as an intermediate host for the filarial nematode Dipetalonema dracunculoides (now Acanthocheilonema dracunculoides) and has been implicated as a potential vector for other pathogens. Native to Africa, it has spread to the Middle East, Asia, and parts of Europe through transport on zoo animals and domestic dogs.

Ricinus
Castor Beans, Castor Oil Plant, Castor Bean, Higuerilla, Mamona
Ricinus is a monotypic genus of flowering plants in the spurge family Euphorbiaceae, containing the single species Ricinus communis. This fast-growing perennial shrub or small tree is native to the southeastern Mediterranean Basin, East Africa, and India, but has become widespread throughout tropical and subtropical regions worldwide. The plant is economically significant as the source of castor oil, extracted from seeds that contain 40–60% oil rich in ricinoleic acid. All plant parts contain ricin, a highly potent water-soluble toxin that makes the seeds especially dangerous if ingested. The species exhibits remarkable morphological variability, with cultivars developed for both ornamental purposes and commercial oil production.

Scaphoideus luteolus
White-banded Elm Leafhopper
Scaphoideus luteolus is a phloem sap-feeding leafhopper native to the eastern United States and the only confirmed vector of Candidatus Phytoplasma ulmi (CPu), the causative agent of elm phytoplasma disease. The species does not cause direct damage through feeding but transmits this pathogen to elm trees (Ulmus spp.), resulting in heavy damage to North American elm populations. It has three developmental stages—egg, nymph, and adult—with overwintering occurring in the egg stage. Both nymphs and adults can acquire and transmit CPu and remain infective for life.

Stenochrus
short-tailed whipscorpions
Stenochrus is a genus of hubbardiid short-tailed whipscorpions (order Schizomida) first described by Ralph Vary Chamberlin in 1922. The genus was historically considered a 'junkyard' taxon containing morphologically disparate species, but integrative systematics using molecular and morphological data has redefined its boundaries. As currently circumscribed, Stenochrus comprises approximately ten species distributed primarily in Mexico, Central America, and the Caribbean. The most widespread species, Stenochrus portoricensis, exhibits exceptional geographic range due to parthenogenetic reproduction and ecological tolerance, with introduced populations established in South America and Europe.

Stictocephala stimulea
Stictocephala stimulea is a treehopper species in the family Membracidae, first described by Van Duzee in 1914. Treehoppers in this genus are characterized by their enlarged, often ornate pronotum that extends over the body like a helmet or thorn. The specific epithet 'stimulea' suggests possible resemblance to or association with stinging organisms, though this refers to appearance rather than actual sting. Like other membracids, this species likely feeds on plant phloem sap using piercing-sucking mouthparts.

Stigmella
pygmy leaf-mining moths
Stigmella is a large genus of minute moths in the family Nepticulidae, commonly known as pygmy leaf-mining moths. Adults typically measure 2–6 mm in wingspan, making them among the smallest Lepidoptera. The genus is characterized by larvae that feed internally in leaf mines of diverse host plants. Many species exhibit narrow host specificity, with individual species restricted to particular plant genera or families. Stigmella contains hundreds of described species distributed across temperate and tropical regions worldwide.

Striacosta
western bean cutworm (for sole species S. albicosta)
Striacosta is a monotypic genus of moths in the family Noctuidae, established by Lafontaine in 2004. The sole species, Striacosta albicosta (western bean cutworm), is an agricultural pest native to North America. The species underwent significant range expansion from the western Great Plains to eastern North America beginning in 1999. Larvae are serious pests of corn and dry bean crops, with documented resistance to Cry1F Bt protein.

Strumigenys membranifera
Bare Mustache Ant
Strumigenys membranifera is a minute trap-jaw ant species native to the Old World tropics that has become a globally distributed tramp species. It is one of only six known Strumigenys species exhibiting thelytokous parthenogenesis, where virgin queens produce diploid female offspring from unfertilized eggs without sperm involvement. Queens retain a functional spermatheca and complete reproductive system despite rarely mating, with males produced only exceptionally. The species has been recorded from numerous regions including Taiwan, Greece (Crete), the Galápagos Islands, and across Asia, reflecting its capacity for human-mediated dispersal and establishment in new environments without mating requirements.

Strumigenys rogeri
Roger's Pygmy Snapping Ant
Strumigenys rogeri is a small dacetine ant species first described by Emery in 1890. It is notable for exhibiting thelytokous parthenogenesis in Taiwan, where virgin queens produce female offspring without mating. This reproductive mode, combined with a short development time of approximately 39 days, may contribute to its success as a tramp ant species. The species belongs to a genus of over 850 species characterized by distinctive trap-jaw mandibles.

Strumigenys silvestrii
silvestrii-group Pygmy Snapping Ants
Strumigenys silvestrii is a tiny dacetine ant in the genus Strumigenys, a group known for their specialized trap-jaw mandibles. Native to South America, this species has undergone significant geographic expansion, establishing populations across the West Indies, southern United States, and more recently in the Old World (Madeira, mainland Portugal, and Macau). It represents the only New World dacetine ant recorded in the Old World. The species exhibits a complex biogeographic pattern with records from both undisturbed forests and human-modified environments.

Thesium
Rootthugs
Thesium is a genus of hemiparasitic flowering plants in the family Santalaceae, with approximately 325 species distributed primarily across Africa, Europe, and Asia. The genus is particularly diverse in South Africa, where roughly half of all species occur. Species in this genus are root hemiparasites that form haustorial connections to host plant roots. The genus has undergone taxonomic revision, with several segregate genera (Austroamericium, Chrysothesium, Kunkeliella, Thesidium) now subsumed within Thesium.

Thyridopteryx
bagworm moths
Thyridopteryx is a genus of bagworm moths (Psychidae) comprising five described species. The genus is best known for T. ephemeraeformis, the evergreen bagworm or North American bagworm, a significant pest of ornamental and landscape plants. Larvae construct protective cases from silk and plant fragments, which they carry throughout their development. The genus exhibits unusual sexual dimorphism: males are winged and capable of flight, while females are wingless and remain within their cases for life.

Tomicus
pine shoot beetles
Tomicus is a genus of bark beetles in the family Curculionidae, described by Pierre André Latreille in 1802. The genus contains at least seven recognized species, including economically significant forest pests such as T. piniperda, T. minor, T. destruens, and T. yunnanensis. These beetles are commonly known as pine shoot beetles due to their distinctive life history involving feeding on pine shoots before trunk colonization. Several species have caused substantial mortality in pine forests across Europe, the Mediterranean region, and southwestern China, with T. yunnanensis described as unusually aggressive in its native range.

Tortistilus wickhami
A North American treehopper in the family Membracidae, recently documented for the first time in Mexico's Baja California peninsula. Previously known from the western and southwestern United States, this species was collected from grapevines in Valle de Guadalupe vineyards during 2023. Its presence in commercial vineyards raises concerns about potential economic impact, as it is suspected to be a candidate vector for grapevine red blotch virus.
