Faxonius immunis
papershell crayfish
Orconectes immunis, commonly known as the papershell crayfish, is a freshwater crayfish native to central North America that has become invasive in parts of Canada. The species has been documented in southwestern Ontario and Lake of the Woods, where it shows preferences for shallow waters with fine substrates and aquatic vegetation. Reproductive studies indicate significant egg mortality during incubation, with females exhibiting size-dependent fecundity. The species has been subject to cellular-level studies of oogenesis, demonstrating intracellular yolk synthesis in oocytes.

Lygus hesperus
Western Tarnished Plant Bug
Lygus hesperus is a significant agricultural pest in western North America, causing extensive damage to cotton, strawberries, alfalfa seed, and other crops. In California alone, annual losses exceed $30 million in cotton and $40 million in strawberries. Adults overwinter in reproductive diapause triggered by short day lengths, resuming activity when conditions improve. The species has been the subject of extensive research on sampling methods, biological control, and insecticide resistance.

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.
