Exenterus amictorius
Exenterus amictorius is an ichneumonid parasitoid wasp introduced to North America that attacks sawfly larvae (Hymenoptera: Diprionidae), particularly during the pre-spinning eonymph stage. The species exhibits adaptive host discrimination behavior that changes during the host's spinning period, lacks discrimination initially but rapidly acquires and maintains this ability. It shows strong positive density-dependent responses to host abundance and has established successfully on multiple diprionid hosts across North America. In multiparasitism situations with the native E. diprionis, E. amictorius consistently survives due to faster larval development.

Lacunicambarus diogenes
devil crayfish, devil crawfish
Lacunicambarus diogenes, commonly known as the devil crayfish or devil crawfish, is a primary burrowing crayfish native to eastern North America. This species constructs and inhabits burrows in wet, muddy terrestrial habitats rather than living in permanent surface water. Its burrowing activities create refugia used by numerous other species, including documented use by eastern cicada killer wasps (Sphecius speciosus) as brooding habitat. The species ranges across the Atlantic Coastal Plain and Piedmont ecoregion from New Jersey to Georgia, with disjunct populations in Louisiana.

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.
