Arhopalus
burnt pine longhorn beetle (A. ferus), black pine sawyer (A. rusticus)
Arhopalus is a genus of longhorn beetles (Cerambycidae: Spondylidinae: Asemini) distributed across the Northern Hemisphere, with several species introduced to the Southern Hemisphere as invasive pests of conifers. The genus comprises approximately 20 described species, with A. rusticus and A. ferus being the most extensively studied due to their economic importance. Species develop in dead or fire-damaged conifer wood, with some exhibiting strong attraction to burnt pine volatiles. Several species produce male-emitted aggregation-sex pheromones containing fuscumol and geranylacetone. Invasive populations in New Zealand, Australia, South America, and South Africa require monitoring at ports and sawmills for timber export compliance.

Cactoblastis
Cactoblastis is a genus of snout moths (Pyralidae) described by Émile Louis Ragonot in 1901. The genus contains five described species native to South America, with C. cactorum being the most extensively studied due to its historical role as a biological control agent. Larvae are specialized internal feeders on cactus cladodes, and the genus is notable for complex collective behaviors in neonate caterpillars. C. cactorum was famously introduced to Australia in 1925 to control invasive prickly pear cacti, achieving significant success, though later spreading to threaten native Opuntia species in other regions.

Orconectes rusticus
Rusty Crayfish
Orconectes rusticus, commonly known as the rusty crayfish, is a freshwater crayfish native to the Ohio River basin in the United States. The species has become a highly successful invasive organism in northern lakes and streams across North America, where it displaces native crayfish through aggressive behavioral dominance. Research has documented its capacity for learned associations involving predator cues, complex social recognition systems using chemical signals, and flexible spatial learning. The species' invasion success stems from a combination of behavioral traits including high aggression, broad habitat tolerance, and efficient resource utilization.

Pacifastacus leniusculus
Signal Crayfish
The signal crayfish is a large North American freshwater crayfish introduced to Europe in the 1960s to replace declining native fisheries. It has become one of the most ecologically impactful invasive decapods in Europe, outcompeting native crayfish and serving as a carrier of crayfish plague (Aphanomyces astaci). The species establishes self-sustaining populations rapidly, with six age cohorts documented within a few years of introduction. It shows sex- and size-specific coloration patterns, with males displaying more saturated and brighter ventral claw surfaces than females, suggesting a role in intraspecific communication.

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.

Trichonephila clavata
Jorō spider, Joro Spider, Parachute spider
Trichonephila clavata, commonly known as the Jorō spider, is a large orb-weaving spider native to East Asia that has become established as an invasive species in the southeastern United States since approximately 2010. First confirmed in Georgia in 2014, it has expanded rapidly across multiple states through a combination of ballooning dispersal and human-mediated transport. The species is notable for its substantial size, striking coloration, and extensive golden webs, but poses minimal risk to humans due to small fangs and docile behavior. Its physiological adaptations—including higher metabolic rate, faster heart rate, and greater cold tolerance than its congener Trichonephila clavipes—suggest potential for continued northward range expansion.
