Blissus occiduus
Western Chinch Bug
Blissus occiduus, the western chinch bug, is a phloem-feeding true bug (Hemiptera: Blissidae) that is a significant pest of warm-season turfgrasses, particularly buffalograss and zoysiagrass. The species exhibits strong host preference hierarchies, with buffalograss being the most preferred host followed by zoysiagrass, though it can survive and reproduce on a broad range of grasses including agronomic crops. Field studies have documented inconsistent control with neonicotinoid insecticides, with thiamethoxam showing particularly rapid degradation in buffalograss tissues compared to imidacloprid and clothianidin.

Cyladini is a tribe of weevils in the family Brentidae, subfamily Apioninae. The tribe includes economically significant pests of sweet potato, particularly the sweetpotato weevil (Cylas formicarius), which causes substantial damage to storage roots in tropical and subtropical production regions. Members of this tribe are characterized by their association with Convolvulaceae host plants and their status as specialized root-feeding pests.

rhinoceros beetles
Pentodontini is the most diverse tribe within the subfamily Dynastinae (rhinoceros beetles), containing over 100 genera distributed across multiple biogeographic regions. Most genera are restricted to a single biogeographic region. The tribe is characterized by substantial morphological diversity, with generic-level identification often relying on mouthpart morphology in females and secondary sexual characters (horns, claw modifications, antennal club length) in males.

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.

Tortopus is a genus of burrowing mayflies in the family Polymitarcyidae, restricted to six species based on cladistic revision: T. igaranus, T. circumfluus, T. harrisi, T. zottai, T. bellus, and T. arenales. The genus is characterized by distinctive morphological synapomorphies including female parastyli receptors with long anterior furrows, entirely flattened penes, and nymphs bearing two subapical tubercles on mandibular tusks. Nymphs construct U-shaped tunnels in clay banks, a behavior that renders them difficult to sample with standard aquatic survey methods.

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.
