Euschistus servus
Brown Stink Bug
Euschistus servus, commonly known as the brown stink bug, is a native North American pentatomid species distributed across Central America and North America. It is a significant agricultural pest in the southern United States, feeding on a wide range of crops including soybeans, cotton, corn, peanuts, peaches, and pecans. The species is highly mobile, capable of dispersing up to 15.9 km in flight mill studies, and exhibits seasonal movement between crop hosts and non-crop habitats. Two subspecies are recognized: E. s. servus and E. s. euschistoides.

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.

Signal Crayfish
The signal crayfish is a large North American freshwater crayfish introduced to Europe in the 1960s to replace declining native fisheries. It has become one of the most ecologically impactful invasive decapods in Europe, outcompeting native crayfish and serving as a carrier of crayfish plague (Aphanomyces astaci). The species establishes self-sustaining populations rapidly, with six age cohorts documented within a few years of introduction. It shows sex- and size-specific coloration patterns, with males displaying more saturated and brighter ventral claw surfaces than females, suggesting a role in intraspecific communication.
