Micaria pulicaria
glossy ant spider, Glossy Ant-spider
Micaria pulicaria is a small ground spider in the family Gnaphosidae, commonly known as the glossy ant spider. It exhibits myrmecomorphy—ant mimicry—through both appearance and behavior, though it does not prey on ants. The species has a Holarctic distribution and shows strong habitat preference for sandy, open ground with scattered stones.

Oreoneta
A genus of dwarf spiders (family Linyphiidae) established in 1894, comprising approximately 30 species distributed across cold-temperate and Arctic regions of the Northern Hemisphere. Most species inhabit high-latitude or high-altitude environments. The genus was revised extensively by Saaristo & Marusik in 2004, resulting in numerous new species descriptions.

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.
