Acroclisoides sinicus
Acroclisoides sinicus is a small pteromalid wasp described from China in 1988. It is an obligate hyperparasitoid that exploits the pupal stage of scelionid primary parasitoids, particularly Trissolcus species, within pentatomid stink bug eggs. Laboratory studies demonstrate extreme host selectivity, with strong preference for Trissolcus mitsukurii over T. japonicus and no exploitation of eupelmid parasitoids. The species has recently expanded to Europe and North America, likely following pathways of its primary parasitoid hosts. Its presence raises concerns for biological control programs targeting invasive stink bugs like Halyomorpha halys.
Euschistus servus
Brown Stink Bug
Euschistus servus, commonly known as the brown stink bug, is a native North American pentatomid species distributed across Central America and North America. It is a significant agricultural pest in the southern United States, feeding on a wide range of crops including soybeans, cotton, corn, peanuts, peaches, and pecans. The species is highly mobile, capable of dispersing up to 15.9 km in flight mill studies, and exhibits seasonal movement between crop hosts and non-crop habitats. Two subspecies are recognized: E. s. servus and E. s. euschistoides.

cristatus
crested pygmy grasshopper, crested grouse locust, northern crested grouse locust
Nomotettix cristatus is a small pygmy grasshopper in the family Tetrigidae, commonly known as the crested pygmy grasshopper or crested grouse locust. It is one of approximately 35 Nearctic species of Tetrigidae. The species exhibits three recognized subspecies with distinct geographic distributions across North America. Like other members of its family, it is characterized by an elongated pronotum that extends over the abdomen, a trait distinguishing pygmy grasshoppers from typical grasshoppers in Acrididae.

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.
