• Dendroctonus mexicanus

  Mexican bark beetle

  Dendroctonus mexicanus is a bark beetle native to Mexico and Central America, recognized as the most widely distributed and destructive bark beetle in Mexico. It colonizes more than 21 pine species and causes significant tree mortality in coniferous forests. The species' population dynamics are strongly influenced by climate variables, particularly temperature and precipitation, with outbreak risk increasing under warmer, drier conditions. It is considered a major forest pest affecting wood supply and ecosystem services.

• 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.
