Allocapnia rickeri
Midwest Snowfly
Allocapnia rickeri is a small winter stonefly in the family Capniidae, commonly known as the Midwest Snowfly. It is one of numerous small, dark stoneflies in the genus Allocapnia that emerge during cold months when few other insects are active. The species has been documented across the central and eastern United States. Like other capniids, it is associated with clean, cold streams and is an important indicator of water quality.

Microterys
Microterys is a large genus of parasitoid wasps in the family Encyrtidae (Chalcidoidea), with its center of distribution in the northern parts of the Northern Hemisphere. Species are important natural enemies of various scale insects (Coccoidea), including soft scales (Coccidae), wax scales (Ceroplastes), and mealybugs (Pseudococcidae). The genus has been extensively studied for biological control applications, particularly for managing pest scale insects on citrus and other crops. Several species have been introduced to new regions as biocontrol agents, including Microterys flavus in California.

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.
